This implements the simple line parser (including the multiline strings
with escape characters). What a difference a good file format makes:
this is nothing like the pain that is XML.
That said, it only does the line/string parsing right now, it doesn't
actually then look at what the lines say. So no human-noticeable
improvements in the actual data shown by subsurface.

If we want to scale to thousands of dives, we'll eventually want to read
the dive computer files lazily when actually needed, but for now we do
everything synchronously. Even if that may actually be slower than
parsing one big XML file.
The git object store is pretty efficient, but especially with some
history, the compression and delta application will certainly not be
free.
This does all the git object unpacking, but none of the actual data
parsing yet. But as part of looking up the file objects, we do get the
dive number (which is in the name of the dive file).

The biggest part of this commit is the comment about the woeful state of
the "git_tree_walk()" interface - the interface is not really very good
for seeing any recursive state, since it just walks the tree pretty much
linearly.
But the only real recursive state we care about is the trip, and in all
normal situations the "trip this dive is in" is the same thing as "what
was the last trip directory we traversed", so a linear walk works fine.
The one exception is if a dive isn't in a trip at all, in which case
"last trip directory" obviously isn't what we want.
But rather than do our own tree walking by hand (and just passing the
trip information in the natural recursive manner when traversing the
tree), we hack around it by just looking at the path to the dive.
That one-liner trivial hack has now generated about 20 lines of
explanation of it.
ANYWAY. With this, we parse the dive and trip hierarchy properly, and
instead of just printing out the data, we might as well insert the dives
and trips into the subsurface data structures.
Note: the only data we have about the dive and trip right now is what is
visible in the directory structure, since we don't look at the actual
dive file at all (not even the name of it, which contains the dive
number). So the end result will be just a sea of empty dives and the
trips they are contained in. The dives have a date and time, and the
trip has a date, though.
So this is *not* useful for actually saving and loading data, but the
data we do load is easily visualized inside subsurface, so as I'm
starting to add real dive data parsing code, it will all be much more
visually satisfying.

Oops. Really stupid bug in event saving, resulting in bad event lines,
that I didn't notice until I started trying to parse them.
The argument order is a bit mixed up, which is partly why this happened.
But considering that this is the worst bug I've hit so far in the saving
code, I guess I shouldn't complain too much.

We want to make sure that we load them in the same order we save them,
and while using the hash made the divecomputer names unique, it didn't
sort them. You couldn't tell with just one or two dive computers, but
if you have three or more dive computers on a dive, the order of any but
the first ended up depending on the ordering of the unique hash
extensions.
So just append a numeric index instead of relying on the hash to make
the names unique. But skip the index if there is just one dive
computer.

I'm ashamed. put_vbuffer() worked perfectly fine for the normal case
when everything fit in our simple buffer on-stack, but the fallback case
was broken in so many ways that I'm just going to go sit in a corner and
cry myself to sleep.
And dammit, I _knew_ how to do it right. I knew you had to do a
"va_copy()" and couldn't just keep re-using 'args'. I've done this
before. But I half-arsed it, and nobody ever noticed, because you
wouldn't do C style format strings for big strings.
"128 bytes is enough for everybody".
And as penance for this idiocy, I just spent too much time trying to
figure out what was wrong in my git loading code when my debug printouts
caused SIGSEGV's.
Sigh.
Anyway, now it should hopefully be correct, and the code is smarter
about things too, not having that extra buffer since we already *have* a
buffer in the "struct membuffer" we are working with.

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.

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.

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.

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.
