e2df38d868 Dive site: add dive site ref-counting
Instead of setting dive->dive_site directly, call the
add_dive_to_dive_site() and unregister_dive_from_dive_site()
functions. In the parser this turned out to be a bit tricky.

c22fd9f4fd Dive sites: prepare for dive site ref-counting
Add a dive site table to each dive site to keep track of dives
that have been added to a dive site. Add two functions to add
dives to / remove dives from dive sites.

Since dive sites now contain a dive table, the order of includes
had to be changed: "divesite.h" now includes "dive.h" and not
vice-versa. This caused some include churn.

31291b1c56 Dive site: set UUID only on save or load
Since the UUID will be overwritten on save and is only used on save
and load, set it only on save or load. For other created dive sites,
leave the UUID field uninitialized.

This means that the UUID will change between saves. Let's see how
the git saver handles that.

f6e7bdc5ef Dive site: add dive site table parameter to dive site functions
To enable undo of dive site functions, it is crucial to work
with different dive site tables. Therefore add a dive site table
parameter to dive site functions. For now, always pass the global
dive site table. Thus, this commit shouldn't alter any functionality.

After this change, a simple search for dive_site_table reveals all
places where the global dive site table is accessed.

40a3e562b0 Cleanup: provide printGPSCoords in C and C++ versions
printGPSCoords() returned a newly allocated C-style string. Most
callers simply made a QString out of it and freed the C-style string.
This is paradoxical, as printGPSCoords internally works with QStrings
and converts them to C-style on return.

Therefore, let printGPSCoords() return a QString and create a
printGPSCoordsC() wrapper for the two C-callers.

04593e8ec4 Cleanup: fix printGPSCoords signature and leaks
The printGPSCoords() function returns a copied C-style string. Since
the owndership is transferred to the caller, the correct return type
is "char *" instead of "const char *".

Thus a number of casts when calling free can be removed.

Moreover a number of callers didn't free the string and thus were
leaking memory. Fix them. Ultimately we might want two versions
of the function: one for QString, one for C-style strings.

28e3413ff6 Add 'location_t' data structure
Instead of having people treat latitude and longitude as separate
things, just add a 'location_t' data structure that contains both.

Almost all cases want to always act on them together.

This is really just prep-work for adding a few more locations that we
track: I want to add a entry/exit location to each dive (independent of
the dive site) because of how the Garmin Descent gives us the
information (and hopefully, some day, other dive computers too).

fc812ea130 core: fix connect call
Fix multiple run-time errors in connect call introduced in 504e912512.
1) Set the proper signature of the signal. 2) make the used slot
a real slot (so move it to the proper section in the header) and
3) set the proper signature for the slot.

Highly unlikely that normal users notice the runtime errors and
possibly unwantend behavior, as this all deals with the subtile GPS

37e98a8d89 Use correct date format
A very very trival fix, for a mysterious issue. When loading
GPS fix data from the server, the string date was parsed with
the format "yyy-M-d". And no, the "yyy" is no typo here, but
was the reason that data from the read from server got a
1/1/1970 data. And when a user decided to upload that data
to the server again, we ended up with 2 copies of the
GPS fix. One with correct data (as originally saved), and
one new with the bogus date.

In order to het rid of those weird 1/1/1970 GPS fixes, users
will have to remove them by hand.

28ae35e7df Make QMap<> access in deleteGpsFix() more idiomatic
To access a QMap<> entry, the value() function is used with a sentinel
as default value. If the sentinel is returned, the code assumes that
the searched for entry doesn't exist.

Make this code more idiomatic by using an iterator and testing for
end().

This fixes a compiler warning, because only one of the elements of
the sentinel was initialized, but the remaining elements were
copied. Harmless, because the code would exit early if it found
the sentinel. Still not nice.

While redoing this function, the entry-not-found message was improved
(adding of function name, space between massage and timestamp) and
elevated from debug to warning level.

56e755b711 Use lrint() for all degrees_t related rounding
In certain places the '(int)' cast is used, while in other the
llrint() or lrint() functions. Make the conversation from degrees
in the 'double' form to the 'int' degrees_t consistent using lrint().

lrint() is the function which should give the best results,
because it accepts a 'double' and results in a 'long'
even if degrees_t is 'int'. If the truncation from 'long' to 'int'
is discarding some of the precision then the next step
would be to turn degrees_t into a 64bit signed integer type.

Possible fix for #625.

597539ce39 Fix double to int truncation in C++ code
Wfloat-conversion enabled for C++ part of the code
Fix warnings raised by the flag using lrint

Original issue reported on the mailing list:
The ascent/descent rates are sometimes not what is expected.
E.g. setting the ascent rate to 10m/min results in an actual
ascent rate of 9m/min.
This is due to truncating the ascent rate preference,
then effectively rounding up the time to reach each stop to 2s intervals.
The result being that setting the ascent rate to 10m/min
results in 20s to ascend 3m (9m/min), when it should be exactly 18s.

2c715542fd Unify handling of QDateTime time zone information
Subsurface uses "local time" which in particular means we never
display time zone information to the user. The user (and our file
format) only sees times like 5pm or 17:00. A better name than
local time (which could mean "local at the dive spot) would
be "watch time", the time displayed by the diver's watch when
she entered the water.

Internally, we store times as time_t, seconds since Jan 1 1970 0:00
UTC. Our convention for conversion between 5pm and time_t as always
been to treat 5pm as if it were UTC.

Then confusion arose since Qt's QDateTime (which is tied to UI elements
like QTimeEdit and similar) is time zone aware and by default assumes
the system time zone. So when we set a QDateTime to 5pm and then later
convert it to time_t we have to take care about the difference between
UTC and the system time zone.

This patch unifies our solution to this problem: With it, we set all
QDateTime's time zone to UTC. This means we don't have to correct for
a time zone anymore when converting to time_t (note, however, the
signedness issue: Qt's idea of time_t is broken since it assumes it
to be unsigned thus not allowing for dates before 1970. Better use the
millisecont variants).

We only need to be careful about time zones when using the current time.
With this convention, when assigning the current time to a QDateTime, we
need to shift for the time zone since its value in UTC should actually be
the watch time of the user who is most likely used to the system time zone.

4ac6f34b16 With patched Qt 5.6 for iOS correctly handle disabled GPS source
Qt 5.6.0 is broken when it comes to using CoreLocationService on iOS.
It doesn't even check if the location service is enabled. My patches fix
that and make Qt set an error code right after service creation. Having
the service creation fail is actually the wrong thing to do because then
Qt switches over to GeoClue and that really isn't helpful for our needs
here.

Additionally, Qt 5.6.0 without my patches doesn't follow the REQUIRED
flow of using the location service as it does not check the access
permissions before accessing the GPS service - without doing so the
GPS service will not run in the background.

71d74f9e3c QML UI: rewrite the commitChanges function
I couldn't figure out how to break this down into small, useful commits.
Part of the problem is that I kept going while working on this and as you
can see from looking at the commit, diff tries so hard to find small code
fragments that moved around, that the diff overall becomes quite
unreadable and it seemed impossible to recreate the sequence of steps
after the fact.

It all started with adding the parsing for the GPS coordinates. But while
testing that code I found several issues with the rest of the function.
Most importantly it seemed ridiculous that we carefully tried to match the
texts that the DiveObjectHelper would create for the various fields,
instead of just using the DiveObjectHelper to do just that. And once I had
converted that I once again realized just how long and hard to understand
that function was getting and decided to break out some of the more
complex parts into their own helper functions.

But of course all this didn't happen in this logical, structured, ordered
way. Instead I did all of these things at the same time, testing,
rearranging, etc.

So in the end I went with one BIG commit that does all of this in one fell
swoop.

This adds four helper functions to deal with start time/date, duration,
location and gps coordinates, and depth of the dive.

To avoid mistakes when dealing with the GPS coordinates, there's another
helper to encapsulate the creation of the dive site and we switched to a
current GPS location.
