Another small tweak to whitespace tool

clang-format doesn't appear to reindent multi line #define statements
correctly - so this hopefully will clean those up.

The included whitespace corrections to the code should stay in place when
using the updated tool.

This includes cleaning up some multi-line comments that were messed up the
last time around as well as a few other minor changes.

Uemis downloader: don't ignore return values from fs operations

In most cases the existing code might have done the right thing, but some
of the hard to reproduce errors might actually stem from the fact that we
have intermittend fs errors. Maybe this addresses things?

Deal with theoretical memory leaks

This is rather academic, but it will make Coverity happy.
If we start running out of memory we should make sure we don't leak any
more memory.

Fix real memory leak

We can't keep the cache around (even though it's tempting) as the next
iteration might change the start time of the planned dive or other
parameters which would make the cached data invalid.

Initial implementation of git save format

This saves the dive data into a git object repository instead of a
single XML file.

We create a git object tree with each dive as a separate file,
hierarchically by trip and date.

NOTE 1: This largely duplicates the XML saving code, because trying to
share it seemed just too painful: the logic is very similar, but the
details of the actual strings end up differing sufficiently that there
are tons of trivial differences.

The git save format is line-based with minimal quoting, while XML quotes
everything with either "<..\>" or using single quotes around attributes.

NOTE 2: You currently need a dummy "file" to save to, which points to
the real save location: the git repository and branch to be used.  We
should make this a config thing, but for testing, do something like
this:

	echo git /home/torvalds/scuba:linus > git-test

to create that git information file, and when you use "Save To" and
specify "git-test" as the file to save to, subsurface will use the new
git save logic to save to the branch "linus" in the repository found at
"/home/torvalds/scuba".

NOTE 3: The git save format uses just the git object directory, it does
*not* check out the result in any git working tree or index.  So after
you do a save, you can do

     git log -p linus

to see what actually happened in that branch, but it will not affect any
actual checked-out state in the repository.

Fix memory leak when parsing a dive fails

Fix theoretical uninitialized read

We should never read cur_pr[cyl] if cyl isn't used during a dive - but for
cylinders that are used cur_pr[cyl] is initialized. But just to catch
errors elsewhere, let's not leave cur_pr[cyl] uninitialized.

Fix compilation with libgit2 0.20

Linus was wrong - the change to the API happened after 0.20 was released.
So libgit2 0.20 still needs the fix.

Fix a crash on changing dives when the ruler is used.

The ruler is a weird beast - it has two child objects that access the
parent to call another function, that call the child functions.

When I updated the plot_info I didn't take that into consideration, what
happened is that when I set the parent's plot_info, the children's
plot_info are still invalid, but the update method is called anyhow.

This patch updates all plot_info's before calling anything else.

Remove the old profile from the main screen of Subsurface

This patch partially removes the code for the old profile from
Subsurface. It removes the use of the old profile on the mainwindow,
but keeping the code in the tree for now.

A bit of code-cleanup also entered this commit because I had to change
every instance of the code that used the old profile.

Now to the real code-cleanup
