cc3a184adf Add initial parser for git trees
It doesn't actually parse the files themselves, but it does walk the
object tree and print out the dives and trips it finds.

6d0011947b Use symbolic names for the git file types
Instead of hardcoding the regular file mode (0100644 is the traditional
Unix S_IFREG file mode with -rw-r--r-- protections), use
GIT_FILEMODE_BLOB (and GIT_FILEMODE_TREE for 040000 - S_IFDIR).

The numbers were historically indeed the regular S_IFREG/S_IFDIR values,
but since those aren't portable, git ended up defining their own.

de6e7d894e Flesh out git save format
This fixes up the writing of the git format to the point that it might
be getting close to complete. In particular:

 - Add subsurface version information into commit message as requested by Dirk

 - Fix missed string quoting ('\' needs to be quoted as '\\')

 - rename "git_save_error()" as "report_error()", since we'll want to
   use this for the loading code too.

 - Improve on dive and trip name generation

 - create a date-based directory hierarchy

 - save dive computer data as individual files

 - actually save the trip information

There might be further changes as I start to actually *read* the git
files, of course.

3b1624ec69 Add a workaround for using post 0.20 git versions of libgit2
Add the following to your qmake command line and things should compile
again:

qmake ... CONFIG+=libgit21-api

8034106219 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.

689fe36030 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.
