The get_depth_units function was expecting an unsigned int as a first parameter.
When it received a negative integer, the function made a cast to an unsigned int,
resulting in a very big number.

If you use the standard naming convention and end your subsurface
filename in ".xml", we will now save away any previous xml file as a
"bak" file before writing a new one.
This can be useful for:
- recovering from mistakes that deleted old dives
- seeing what changed (ie you can do things like "diff -u xyz.bak
xyz.xml") after doing some operation and saving the result.
However, this does only a single level of backups - if you save twice,
you will obviously have lost the original. I'd strongly encourage some
external backup system in addition to this very simplistic backup.

rint() is "round to nearest integer", and does a better job than +0.5
(followed by the implicit truncation inherent in integer casting). We
already used 'rint()' for values that could be negative (where +0.5 is
actively wrong), let's just make it consistent.
Of course, as is usual for the messy C math functions, it depends on the
current rounding mode. But the default round-to-nearest is what we want
and use, and the functions that explicitly always round to nearest
aren't standard enough to worry about.

SAC should be calculated in relationship to surface pressure, not "1 bar".
I also realize that we have a few other cases where we do the same
mistake: the partial pressure calculations do things like
po2 = o2 / 1000.0 * depth_to_mbar(sample->depth.mm, dive);
which is wrong as well - the partial pressure is also relative to
standard atmospheric pressures.

This adds an entry to the dive list context menu to load images. The user
can select image files and set a time offset to align camera and dive
computer clocks.
Using the exif time stamp the images are tried to match to the times of
the selected dives (with a grace period of an hour before and after the
dive). Upon success an event of type 123 is created per image with the
string value being the path to the image. Those images are displayed as
thumbnails in the profile. If the matching dive does not yet have a geo
location specified but the image provides one it is copied to the dive
(making the camera a poor man's companion app).
This patch includes easyexif https://code.google.com/p/easyexif/ which is
originally under a New BSD License to parse the image meta data.
This commit includes a new test dive dives/test31.xml with a matching
image wreck.jpg to try out the functionallity.

Have images on the map
Have the images clickable
Have a proper picture viewer

Some dive computers will always download all tanks that they store, not
just the ones used in a dive. Most people only want to see the tanks that
they actually used during the dive (and for the others there's an option
to go back to the old behavior, just in case).
All this is only in memory / during runtime. If the dive computer provided
the extra data we will not throw it away.

It's currently only used for the setting of the cylinder switching
depth, but now that one should work with user-specified units (so you
can set a max depth in feet even if you use metric, and vice versa).
In the future, if we also make the unit preferences something you can
pass in (with user preferences as a default argument value), we might
want to use this for parsing the XML too, so that we'd honor explicit
units in the XML strings. But the XML input unit preferences are not
necessarily at all the same as the user preferences, so that does
require us to extend the conversion functions to do possibly explicit
unit preference selection.

The C library doesn't use const char pointers for legacy reasons (and
because you *can* modify the string the end pointer points to), but
let's do it in our internal implementation just because it's a nice
guarantee to have.
We actually used to have a non-const end pointer and replace a decimal
comma with a decimal dot, but that was because we didn't have the fancy
"allow commas" flags. So by using our own strtod_flags() function, we
can now keep all the strings we parse read-only rather than modify them
as we parse them.

This is a bit painful, but we basically walk the samples and pick the
valid tank from the events. And then we do a simple discrete integration
to figure out the mean depth per tank and duration per tank. And then we
assemble all that into per tank statistics.
Strangely the value calculated here seems slightly higher than one would
expect from the overall SAC rate. This inconsistency should be
investigated a bit further, but my guess it it's based on the assumption
that the DC provided mean depth is possibly more accurate than what we can
calculate from the profile.

This tries to speed up XML loading for large XML files (and thus
subsurface startup times) by trimming the fat off our own matching code.
The actual libxml overhead (particularly string allocation) tends to be
the dominant part, so this only speeds up a big load by about 12% for me,
but hey, it can be noticeable. Dirk's example nasty 175MB xml file with
~5200 dives takes "only' 7.7 seconds to load, when it used to take 8.8s.
And that's on a fast machine.
For smaller xml files, the dynamic loading costs etc startup costs tend to
be big enough that the xml parsing costs aren't as noticeable.
Aside from switching the node names around to "little endian" (ie least
significant name first) format to avoid some unnecessary strlen() calls,
this makes the nodename generation use a non-locale 'tolower()', and only
decodes up to two levels of names (since that's the maximum we ever match
against anyway).
It also introduces a "-q" argument to make startup timing easier. Passing
in "-q" just makes subsurface quit imediately after doing all necessary
startup code.
