There is still a bug involving octopus merges, somewhere, but this gets normal
merges correct, so it's still an improvement over the existing version.

With the change in default, "git add ." on kernel dir is about
twice as fast as before, with only minimal (0.5%) change in
object size. The speed difference is even more noticeable
when committing large files, which is now up to 8 times faster.
The configurability is through setting core.compression = [-1..9]
which maps to the zlib constants; -1 is the default, 0 is no
compression, and 1..9 are various speed/size tradeoffs, 9
being slowest.

Earlier change broke "git describe A B" among other things.
Revert it for now, and clean the commits smudged by
get_merge_bases using clear_object_marks() function. For
complex commit ancestry graph, this is way cheaper as well.

Change get_merge_bases() to be able to clean up after itself if
needed by adding a cleanup parameter.
We don't need to save the flags and restore them afterwards anymore;
that was a leftover from before the flags were moved out of the
range used in revision.c. clear_commit_marks() sets them to zero,
which is enough.

It had the wrong test for whether a commit was a merge. What it did was to
say that a non-merge has exactly one parent (which sounds almost right),
but the fact is, initial trees have no parent at all, but they're
obviously not merges.

The rev-list command that is recent enough can filter commits
based on paths they touch, so use it instead of generating the
full list and limiting it by passing it with diff-tree --stdin.

This IMNSHO cleans up the object hashing.
The hash expansion is separated out into a function of its own, the hash
array (and size) names are made more obvious, and the code is generally
made to look a bit more like the object-ref hashing.
It also gets rid of "find_object()" returning an index (or negative
position if no object is found), since that is made redundant by the
simplified object rehashing. The basic operation is now "lookup_object()"
which just returns the object itself.
There's an almost unmeasurable speed increase, but more importantly, I
think the end result is more readable.

With history simplification, we still show merges that are required
to make the history _complete_, i.e. say that you had:
a
|
b
/ \
c d
| |
and neither "a" nor "b" actually changed the file, but both "c" and "d"
did: in this case we have to leave "b" around just because otherwise there
would be no way to show the _relationship_, even if "b" itself doesn't
actually change the tree in any way what-so-ever.
It would make sense to make that further simplification if the
"--parents" flag wasn't present. In that case the user is
literally asking for a list of commits and is not interested in
the relationship between them.
This patch also fixes a real bug. Without this patch, the
"--parents --full-history" combination (which you'd get if you
do something like
gitk --full-history Makefile
or similar) will actually _drop_ merges where all children are identical.
That's wrong in the --full-history case, because it means that the graph
ends up missing lots of entries.
In the process, this also should make
git-rev-list --full-history Makefile
give just the _true_ list of all commits that changed Makefile (and
properly ignore merges that were identical in one parent), because now
we're not asking for "--parent", so we don't need the unnecessary merge
commits to keep the history together.

'A...B' is a shortcut for 'A B --not $(git-merge-base --all A B)'.
This XOR-like operation is called symmetric difference in set
theory.
The symbol '...' has been chosen because it's rather similar to the

Add get_merge_bases_clean(), a wrapper for get_merge_bases() that cleans
up after doing its work and make get_merge_bases() NOT clean up.
Single-shot programs like git-merge-base can use the dirty and fast
version.
Also move the object flags used in get_merge_bases() out of the range
defined in revision.h. This fixes the "66ae0c77...ced9456a

There are a few special places where some programs accessed the object
hash array directly, which bothered me because I wanted to play with some
simple re-organizations.
So this patch makes the object hash array data structures all entirely
local to object.c, and the few users who wanted to look at it now get to
use a function to query how many object index entries there can be, and to
actually access the array.

In the repacking window, if both objects we are looking at already came
from the same (old) pack-file, don't bother delta'ing them against each
other.
That means that we'll still always check for better deltas for (and

avoid the delta creation 99% of the time.

This fleshes out the code that generates a three-way merge of a set of
blobs.
It still actually does the three-way merge using an external executable
(ie just calling "merge"), but the interfaces have been cleaned up a lot
and are now fully based on the 'mmfile_t' interface, so if libxdiff were
to ever grow a compatible three-way-merge, it could probably be directly
plugged in.
It also uses the previous XDL_EMIT_COMMON functionality extension to
libxdiff to generate a made-up base file for the merge for the case where
no base file previously existed. This should be equivalent to what we
currently do in git-merge-one-file.sh:
diff -u -La/$orig -Lb/$orig $orig $src2 | git-apply --no-add
except it should be much simpler and can be done using the direct libxdiff
interfaces.
