Most of the warnings are IMHO false positives:
e.g.: an enum variable is initialized in a switch statement that has a case for
each possible enum value - yet gcc 4.8 warns that it could be used
uninitialized;
or: two variables are initialized together in the code - second one of them
is previously initialized to -1 at declaration time, both are initialized
in an if (second one == -1) clause - so they are guaranteed to both be
initialized...
I did not "fix" those as the code is actually correct.
But there are three spots where it catches things that could indeed go wrong
(with odd input data in one of them).
This commit also adds a check to only call g_type_init() for older versions of
glib as in newer ones it is deprecated.

In commit b6c9301e58 ("Move more dive computer filled data to the
divecomputer structure") we moved the fields that get filled in by the
dive computers to be per-divecomputer data structures.
This patch re-creates some of those fields back in the "struct dive",
but now the fields are initialized to be a reasonable average from the
dive computer data. We already did some of this for the temperature
min/max fields for the statistics, so this just continues that trend.
The goal is to make it easy to look at "dive values" without having to
iterate over dive computers every time you do. Just do it once in
"fixup_dive()" instead.

This clarifies/changes the meaning of our "cylinderindex" entry in our
samples. It has been rather confused, because different dive computers
have done things differently, and the naming really hasn't helped.
There are two totally different - and independent - cylinder "indexes":
- the pressure sensor index, which indicates which cylinder the sensor
data is from.
- the "active cylinder" index, which indicates which cylinder we actually
breathe from.
These two values really are totally independent, and have nothing
what-so-ever to do with each other. The sensor index may well be fixed:
many dive computers only support a single pressure sensor (whether
wireless or wired), and the sensor index is thus always zero.
Other dive computers may support multiple pressure sensors, and the gas
switch event may - or may not - indicate that the sensor changed too. A
dive computer might give the sensor data for *all* cylinders it can read,
regardless of which one is the one we're actively breathing. In fact, some
dive computers might give sensor data for not just *your* cylinder, but
your buddies.
This patch renames "cylinderindex" in the samples as "sensor", making it
quite clear that it's about which sensor index the pressure data in the
sample is about.
The way we figure out which is the currently active gas is with an
explicit has change event. If a computer (like the Uemis Zurich) joins the
two concepts together, then a sensor change should also create a gas
switch event. This patch also changes the Uemis importer to do that.
Finally, it should be noted that the plot info works totally separately
from the sample data, and is about what we actually *display*, not about
the sample pressures etc. In the plot info, the "cylinderindex" does in
fact mean the currently active cylinder, and while it is initially set to
match the sensor information from the samples, we then walk the gas change
events and fix it up - and if the active cylinder differs from the sensor
cylinder, we clear the sensor data.

This commit makes deco handling in Subsurface more compatible with the way
libdivecomputer creates the data. Previously we assumed that having a
stopdepth or stoptime and no ndl meant that we were in deco. But
libdivecomputer supports many dive computers that provide the deco state
of the diver but with no information about the next stop or the time
needed there. In order to be able to model this in Subsurface this adds an
in_deco flag to the samples. This is only stored to the XML file when it
changes so it doesn't add much overhead but will allow us to display some
deco information on dive computers like the Atomic Aquatics Cobalt or many
of the Suuntos (among others).
The commit also removes the old event based deco code that was commented
out already. And fixes the code so that the deco / ndl information is
stored for the very last sample as well.

The initial downloader reused the XML parsing of SDA files that was
implemented early in order to support the information extracted from the
SDA with the java applet. But creating this intermediary XML file and
handing it off to the XML import function always seemed like an ugly way
to do things. This became even more obvious when adding more features to
the Uemis downloader.
This commit completely changes the downloader to instead create dives and
record them directly.
This also adds support for divespots (which are stored in a seperate
database that needs to be queried after the divelog and dive entries have
been combined - the Uemis firmware clearly was written by monkeys on
crack - oh wait: I'm trusting these same people to get the deco right?).
This commit leaves the SDA import capability in the XML parser intact.
I'll remove that later. Because of this it actually adds a few lines of
code, but the overall change will be a substantial code deletion.

Actually, it's even better than that. Thanks to the new divecomputer
datastructure we can now simply look up in the dive_table which dives have
been downloaded from this specific Uemis SDA.
This patch removes the old gconf based code - which leads to one
unfortunate problem: the first time a Uemis SDA owner runs this version of
Subsurface against their data file ALL dives will be downloaded again
(which may not be a bad thing as we have improved a few other details of
Uemis support so now they get their deco information, surface pressure and
other data that we have started to support since 2.1). Still, this is not
ideal. But I didn't want to keep the legacy code around since this new
solution is so much cleaner.

I was a little too eager to add the deco feature to Subsurface. Jef and I
went back and forth a few more times and the definition of those events
changed. I guess I shouldn't have commited that code until the
corresponding libdivecomputer code had been pushed.
This commit now brings us in sync with the current master of
libdivecomputer (but should compile with 0.2 as well - only deco events
won't work then).
One issue that I see is that deco / ndl aren't really a good fit for the
event model. I actually disabled the drawing of the little yellow
triangles for ndl events as for example on the Uemis those events are
created whenever the remaining non stop time changes - and that can be
every few seconds.
The correct solution may be to treat this as a function of the samples,
but for now this works and is tested with both OSTC and Uemis SDA.

This simplifies the vendor/product fields into just a single "model"
string for the dive computer, since we can't really validly ever use it
any other way anyway.
Also, add 'deviceid' and 'diveid' fields: they are just 32-bit hex
values that are unique for that particular dive computer model. For
libdivecomputer, they are basically the first word of the SHA1 of the
data that libdivecomputer gives us.
(Trying to expose it in some other way is insane - different dive
computers use different models for the ID, so don't try to do some kind
of serial number or something like that)
For the Uemis Zurich, which doesn't use the libdivecomputer import, we
currently only set the model name. The computer does have some kind of
device ID string, and we could/should just do the same "SHA1 over the
ID" to give it a unique ID, but the pseudo-xml parsing confuses me, so
I'll let Dirk fix that up.

With this commit we not only use the getDivelogs command but also the
getDive command for each of the dives that was downloaded. Oddly, that
makes quite a bit of redundant (and at times slightly contradictory) data
available, but also many new things.
We now get weight, suit and notes that were stored with a dive in the
logbook on the divecomputer. There are a ton more data available that we
don't use, yet. For example information about altitude, a decoindex, dive
type and dive activity, other equipment information, etc.

Subsurface (and how I want to present this - after all most of this is not

Here is what Linus reported:
I think you have made a mistake in trying to translate some of
libdivecomputer.c
Translating some of those things based on locale is *wrong*, because
they are saved in the XML file.
That covers at least the warnings: they'll get translated when you
import them, and then saved to the XML file as that translation, but
now if you start subsurface in another locale, they will not get
translated back.
So translating XML file contents is fundamentally buggy. It just
shouldn't be done.
So all the "translations" for the event handling are buggy, and
generate crap. Please don't do that. Leave them as English.
And of course he is absolutely right. However, instead of not translating
them at all, this commit fixes things a better way - we now mark the
strings for translation but store the original English strings everywhere
(in the in-memory data structure as well as in the XML file). Only when we
actually display something on the screen (in a tooltip or in the filter
dialog) do we actually translate the strings into the native language.
This should address both Linus' issue and the desire to have localized
event texts.

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

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.

I guess no one has ever tried to import Uemis dive data under Windows.
The glib-2 libraries for Windows (at least the ones that are part of the

whole program to be compiled with Windows packing rules for structures.
That broke the structure we use for decoding Uemis binary data.

values but instead two 8bit values and assemble them in the actual code.

This is something I wanted to do for a while. Every uemis sample is simply
a packed structure with no padding. Instead of grabbing random bytes from
the middle of an unstructured data blob let's just define the structure
and access its members.
And while we do that, add support for the more useful uemis events as
well.
A couple of the warnings are disabled by default (compile time flag) as
they are just crazy - any normal dive will give you dozens and dozens of
speed warnings. Same goes for the PO2 green warning (I haven't looked but
this seems to trigger on a PO2 over 1.0 or something). Completely useless
and just hides actually useful info.
I still want to redo the way we visualize events in general - just
printing the text ontop of the profile really is suboptimal. Especially as
the uemis really seems to love to repeat several of the warnings quite
frequently.

We can instead 'Open' these files as they are just bastardized XML files.
This gets us back to a more consistent point where 'Import' gets data
directly from the dive computer (and hopefully soon we will add the
ability to load a dive directly from a uemis SDA to libdivecomputer),
and 'Open' loads a file from the filesystem of the computer we are
running on (this last sentence phrased so awkwardly as the uemis Zurich
SDA is a computer and presents a file system when connected via USB - it
just doesn't have the dive data in an accessible format in that file
system).
As a bonus we get to throw away quite a bit of code (the uemis specific
file handling, mini-XML parser with helper functions, the file open dialog
in the importer). Yay!

There are a few interesting issues with this:
- this requires a change to the SDA file format; thankfully I control that
format, too (the default files are not valid XML files)
- once again, the fact that adding samples can change the dive pointer
messes with me - I decided to change the interface of ALL of the
XXX_dive_match functions to take a struct dive**
I know this is not ideal as all the other functions don't need that -
but I would have hated the inconsistency
- there is the issue that we now overload two _different_ uemis formats in
the same function - that's certainly a potential point of confusion
- a minor detail is the problem that the SDA format is kinda odd to parse
and that we trigger on the duration field by it being the only float.
Yeah, that's not ideal - but again, I control the format, so I _know_
this is true.

Admittedly the cuft ratings are stupid, but still, it's not that hard.
In order to correctly describe a tank based on the cuft system you need to
know the cuft AND the working pressure. But the uemis Zurich always
assumes that the working pressure is 200bar. That's pretty close to
3000psi and therefore works "good enough" for Aluminum tanks - but in
general this will of course fail (e.g. for HP or LP tanks).
