here an fix to make this work on win32 and also solve a potential issue of type:
(subsurface.bin:19441): Gtk-CRITICAL **: IA__gtk_entry_set_text:
assertion `GTK_IS_ENTRY (entry)' failed

my commit message is explicit on the reasons:
------------------------
When called from the "dive edit" dialog the, map windows seems
inactive on Windows. It cannot accept focus and is also behind all
other application windows.

There are a couple of important new calls in gps.c:show_map():
gtk_window_set_transient_for(GTK_WINDOW(*window), GTK_WINDOW(main_window));
(^ docs say gtk "may" call this one for us, on what condition - not specified)
gtk_window_set_modal(GTK_WINDOW(*window), TRUE);
(^ broken on ubuntu 12.04, but needed on Win32))

Making the window transient for the main window and also modal for
the entire application's window stack (or at least try).

Older versions of gtk+2 and also in the most recently tested
libgtk2.0-0 2.24.10-0ubuntu6, seem not to recognize the significance
of gtk_window_set_modal() and the call does not work as expected.
This forces us to check if the dialog from which the call originated
exists, since its possible to close it _while_ the map widget is active.

More specifically, we check in info.c if the location_update.entry pointer
was set to NULL before performing actions with in the update_gps_entry()
callback.
------------------------

also removed the gtk_window_present() call as it seemed redundant post
these changes (?).

This cleans up our handling of combo boxes and all the duplicated
completion logic, and simplifies the code.

In particular, we get rid of the deprecated GtkComboBoxEntry.  While it
made some things easier, it made other things harder.  Just using
GtkComboBox and setting that up correctly ends up being simpler, and
also makes the logic work with gtk-3.

332d372b80 Pick GPS coordinates of dive location via map widget
I have some concerns about the way this is implemented - especially the
use of gtk_grab_add to make the map widget work has me worried. But it
seems to work and survived some test cases that I threw at it.

The GtkButton with the Pixmap looks a little off on my screen, but this
way it was easy to implement. Feel free to come up with a better design.

546fecd850 UTF8 aware parser for some more GPS formats
I'm sure there are better ways to do this, but this appears to grok most
rational formats I was able to find. NSEW or positive/negative numbers.
Decimal degrees (WGS84) or degrees and decimal minutes (that's what most
GPSs seem to provide). I'm sure there are still corner cases that confuse
it, but it seemed reasonably robust in testing.

I don't really love the ';' as separator but that solves the obvious
problem with locales that use a decimal comma.

1cbffeaaf5 Allow manual entry of GPS coordinates
This implementation gives the user the ability to add GPS coordinates to
the dive location. It works as expected in multi-dive edit scenarios. It
has two major flaws:
- it only support WGS84 style coordinates - it should instead be
  intelligent enough to parse the common formats, at least using NSEW
  instead of sign and understanding minutes and seconds instead of decimal
  degrees
- but in reality, it really needs to support a map picker

b6c9301e58 Move more dive computer filled data to the divecomputer structure
This moves the fields 'duration', 'surfacetime', 'maxdepth',
'meandepth', 'airtemp', 'watertemp', 'salinity' and 'surface_pressure'
to the per-divecomputer data structure.  They are filled in by the dive
computer, and normally not edited.

NOTE! All actual *use* of this data was then changed from dive->field to
dive->dc.field programmatically with a shell-script and sed, and the
result then edited for details.  So while the XML save and restore code
has been updated, all the displaying etc will currently always just show
the first dive computer entry.

868a2cc090 Split up preference data structure definition into 'pref.h'
.. and rename the badly named 'output_units/input_units' variables.

We used to have this confusing thing where we had two different units
(input vs output) that *look* like they are mirror images, but in fact
"output_units" was the user units, and "input_units" are the XML parsing
units.

So this renames them to be clearer.  "output_units" is now just "units"
(it's the units a user would ever see), and "input_units" is now
"xml_parsing_units" and set by the XML file parsers to reflect the units
of the parsed file.

bf395ebf45 Avoid pointless calls to dive planner
Stupid Gtk. Seriously. So in order to get a notification if the user
selects the drop down for the gas with the mouse I need to connect to the
"changed" signal for the combobox. But that also fires whenever the user
types something into the GtkEntry. Which means we once again get called
for all kinds of silly partial names.

Instead we want to handle the manual entry in the "focus-out" callback
(the user has hit tab or something else to move away from the GtkEntry -
let's assume that this is the text he wants us to use) and only respond to
the changed signal on the combobox if the user selected something from the
dropdown.

The easiest way to do that (I think) is to check the text with the strings
stored in the model. If this indeed matches a string stored in the model
then most likely this is something the user selected from the dropdown.
But more importantly if it isn't in the model, then we KNOW that this is
just a partial string that was typed in. And we can ignore that one.

febcbd6325 Add the ability to edit the date/time of a dive
This can cause some fun unintended side effects - especially when the dive
is part of a trip and the new date/time moves this into a different trip.
Instead, trips get split and the overall result is consistent, but a bit
unexpected.

But since this is designed to help people right after a dive import in
case the clock on the dive computer was wrong, my guess is this won't ever
be a problem for actual users.

01f1ccff14 Add support for visibility tracking and allow manual entry air temp
Turns out we had a data field for visibility as a length unit - but never
used it. I can never guess how much visibility we actually had on a dive -
but I think most everyone can assign a rating between abysmal (zero stars,
"I couldn't read my dive computer even right in front of my mask" - trust
me, I had some of those dives) to amazing ("five stars, I could see farther
than I though possible" - and I had one or two of those, too). So I
changed this to an integer and am re-using the star infrastructure we have
for the overall dive rating.

When displaying this I was dismayed that we are running out of space in
the "Dive Notes" notbook. So I moved this to the "Dive Info" notebook.
This is not consistent and not logical. I think we need to revisit the
notebooks and think about what we want to display where.

While adding the infrastructure to manually enter the visibility I went
ahead and added the ability to manually enter the air temperature as well
(that was one of the things missing in the previous commit).

88a321c983 Allocate memory for and truncate strings that go into the title bar
info.c:show_dive_info() uses buffers of 80 char, which might not be enough
for all unicode strings to fit. The function snprintf() can be used to
truncate a string to the maximum buffer length, however this should
not be used with unicode strings, since it can split the bytes of a
wide char, causing some corruption.

Instead of a fixed buffer we now allocate/free memory for the title text and
attempt to more safely truncate user entered text by using g_utf8_strlen()
and g_utf8_strncpy(). Long unicode filenames still remain a responsibility
of the user, but they should be now safe as well. On the other hand the string
formed by the function divename() and the variable maxlen should be
monitored by developers to accommodate all translations.

dbae888abc Handle dates and a "calculated plural" in translations
This looks like a massive commit mainly because of the line number changes
in the .po files. That sadly hides what really happened here:

- the places where we manually build dates have now been localized
- the one place where we did the English "calculated plural" has been
  modified so that it now can be correctly translated (in English this
  just adds an 's' to the noun if the number is != 1 - in other languages
  this tends to be much more complicated)

I then updated the two German translations to take advantage of the new
constructs. And while I was at it, I changed the translation Trip->Gruppe
to Trip->Reise as that seemed much more appropriate.
I also fixed another error in the German translation where I translated
"dive time" as "Startzeit" - but in the context it was "Dauer".

99846da77f Conversion to gettext to allow localization
This is just the first step - convert the string literals, try to catch
all the places where this isn't possible and the program needs to convert
string constants at runtime (those are the N_ macros).

Add a very rough first German localization so I can at least test what I
have done. Seriously, I have never used a localized OS, so I am certain
that I have many of the 'standard' translations wrong. Someone please take
over :-)

Major issues with this:

- right now it hardcodes the search path for the message catalog to be
  ./locale - that's of course bogus, but it works well while doing initial
  testing. Once the tooling support is there we just should use the OS
  default.

- even though de_DE defaults to ISO-8859-15 (or ISO-8859-1 - the internets
  can't seem to agree) I went with UTF-8 as that is what Gtk appears to
  want to use internally. ISO-8859-15 encoded .mo files create funny
  looking artefacts instead of Umlaute.

- no support at all in the Makefile - I was hoping someone with more
  experience in how to best set this up would contribute a good set of
  Makefile rules - likely this will help fix the first issue in that it
  will also install the .mo file(s) in the correct place(s)

  For now simply run

  msgfmt -c -o subsurface.mo deutsch.po

  to create the subsurface.mo file and then move it to
  ./locale/de_DE.UTF-8/LC_MESSAGES/subsurface.mo

  If you make changes to the sources and need to add new strings to be
  translated, this is what seems to work (again, should be tooled through
  the Makefile):

  xgettext -o subsurface-new.pot -s -k_ -kN_ --add-comments="++GETTEXT" *.c
  msgmerge -s -U po/deutsch.po subsurface-new.pot

  If you do this PLEASE do one commit that just has the new msgid as
  changes in line numbers create a TON of diff-noise. Do changes to
  translations in a SEPARATE commit.

- no testing at all on Windows or Mac
  It builds on Windows :-)

6ae67f96f8 Update cylinder info properly
The "cylinders_equal()/copy_cylinders()" functions were buggered, and
only checked (and copied) the cylinder type.  That was on purpose, since
you do want to be able to change the type of a cylinder without changing
the gasmix of the cylinder.

HOWEVER, the reverse is also true: you may want to change the gasmix of
a cylinder without changing the type.

So it's not that the type of the cylinder is special - it's that the
type and the gasmix should be considered separately.

Do that properly for the equipment editing case.

4f920b71aa dive-time widget: fix incorrect use of timestamp_t
I did a global search-and-replace to make all "time_t" users use the
internal subsurface 64-bit "timestamp_t" type instead, but we have one
case that still uses the system time functions: the use of "localtime()"
in the dive_time_widget().

Everywhere else we always just use UTC for all our time handling, and we
don't really ever care about the local timezone etc.  However, for the
dive time widget, we initialize the calendar widget to the current time,
which obviously does want to take the local timezone into account, so
there we end up using the whole system time handling code.

So that one should continue to use time_t, even if it might have the
year-2038 problem.  We also don't care about the fact that it's not
thread-safe, since this is just initializing the widget which definitely
doesn't happen threaded.

c804c4e02e Partial rewrite of the dive trip code
This introduces a new data structure for dive trips - reuseing the struct
dive just got way too messy.

The dive_trip_t datastructure now allows the code to remember if the trip
was auto generated or if its time stamp changed when dives where added to
the trip during auto generation.

The algorithm also distinguishes between dives that were intentionally
added to a trip (either in an XML file or by adding them to trip in the
UI) and dives that were added to trips via autogen. Saving dives that were
added to trips via autogen makes that assignment "intentional".

With this partial rewrite several of the oddities of the old code should
be resolved - especially turning autogen on and off again should get the
divelist back to the previous stage.

Also, when dives are merged during file open or import we now try to pick
the correct tripflag (instead of just ignoring the tripflag completely and
resetting it to TF_NONE by mistake).

Finally, the dive trip debugging code got more verbose and is trying
harder to detect issues at the earliest time possible.

matches our original "utc_mktime()".

2.0 we'll bring it back into master.

I made a few small clean-ups during the merge, but the merge itself is
very much straight forward.

41d3a11ee3 Fix a long standing bug when editing dives
Calling edit from the context menu creates a combined editing widget that
contains both dive info and equipment. When editing cylinders or
weightsystems from that widget and confirming those edits with OK those
changes were already committed to the current_dive - regardless on which
dive the user clicked. Worse, even when the user clicked Cancel in the
edit widget, any changes to the equipment stayed in effect.

This had especially confusing consequences when editing multiple dives.

As a workaround this commit adds a global edit_dive variable. This fake
dive is edited by the secondary editing widgets and if the user accepts
changes with OK then they are copied over to the current dive (or all
selected dives in multi dive editing mode).

c3debc10fd Allow modification and edits of trips
Now that we can load and store trips we needed to add the capability to
manipulate those trips as well.

This commit allows us remove a dive from a trip via a right click
operation on the dive list.

The commit also adds code to split a trip into two, to merge two trips and
to create a new trip out of a top level dive.

To make all that useful this commit changes the right-click on the dive
list to identify and act on the record we are actually on (instead of
acting on the selection).

The right-click menu ("context menu") changes depending which divelist
entry the mouse pointer is on - so different operations are offered,
depending on where you are.

We also add simplistic editing of location and notes for a trip (but the
notes are never displayed so far).

To make our lives easier this commit adds a link from the dive to the dive
trip it is part of. This allowed to hugely simplify the auto trip
generation algorithm (among other things). The downside of this change is
that there are now three different ways in which we express the
relationship of dives and trips: in the dive_trip_list, in the tree_model,
and with these pointers.  Somehow this screams that I should rethink my
data structures...

9380f78c82 Do some whitespace cleanup
The previous commit was a patch from Lubomir, which also had some
whitespace fixes (to go with some new whitespace bugs to replace them)
in it.

I removed the whitespace changes from that patch (don't mix whitespace
fixes with other fixes, unless they are on the same lines!) but decided
to look for other whitespace issues, and this is the result.

I left the non-C files alone, some of the spec and script files also
have whitespace at the end of lines etc.

21fd73515f Ignore Nitrox/He seetings when editing cylinders for multiple dives
When figuring out which cylinders to change in a multi-dive edit, we
already ignored the beginning and end pressures. But it turns out to make
more sense to also ignore the Nitrox / Helium settings.

Imagine you do a number of dives - for some reason your dive computer
records the wrong cylinder size in the downloaded logfile (like my uemis
does all the time). Dives will likely have different Nitrox percentage,
but you should still be able to simply fix the cylinder size for all dives
at once.

666538ec77 Add helper 'for_each_dive()' dive iterator
It's an easy thing to do, but the for-loop ends up being pretty ugly, so
hide it behind the macro.

It would be even prettier with one of the (few) useful C99 features:
local for-loop variables.  However, gcc needs special command line
options, and other compilers may not do it at all. So instead of doing

   #define for_each_dive(_x) \
      for (int _i = 0; ((_x) = get_dive(_i)) != NULL; _i++)

we require that the user declare the index iterator too, and the use
syntax becomes

   for_each_dive(idx, dive) {
	... use idx/dive here ...
   }

And hey, maybe somebody actually will want to use the index, so maybe
that's not all bad.

e46688d694 Fix single-dive editing oddity
The multi-dive case does fine, but the single-dive case (used when
adding a dive, for example) was somewhat confused between the dive index
(which is the location in the dive array) and the dive number.

Fix this by just passing the dive pointer instead (where NULL means to
use the current dive selection).

df1f506b4e Check if multi-dive editing is actually needed
Context menu callbacks always invoke edit_multi_dive_info(-1) instead of
edit_dive_info.  Since -1 means "all selected", it was impossible to edit
dive notes through the context menus.  This commit makes the function
check if multiple dives are actually selected.

972669d636 Rework dive selection logic
This completely changes how we keep track of selected dives: instead of
having an array listing the selection ("selectiontracker") or trusting
the gtk selection information, just save the information about whether a
dive is selected in the dive itself.

That makes it trivial to keep track of the state of selection across
group collapse/expand events, or when changing the tree view model.  It
also ends up simplifying the code and logic in other ways.

HOWEVER, it does currently (re-)introduce an annoying oddity with gtk:
if you collapse a dive trip that has individual selections, gtk will
forget those selections ("out of sight, out of mind"), and when you do
*new* selections, the old hidden ones remain.

So there's some games required to make gtk do sane things.  We may need
to either explicitly drop selections when collapsing trips, or make sure
the group entry gets selected when collapsing a group that has
selections in it. Or something.

There may be other issues introduced by this too.

bc53bbb10b Select better (?) default date for adding new dive
We now pick one hour after the end of the currently selected dive as the
default starting time for the new dive to be added.  If multiple dives
(or no dives) are selected, we default to current time as before.

The "one hour after the end" is just a random (but not unreasonable)
assumption for the surface time if you add multiple dives.
