Extract "log [diff options]" parser out.

Merging of the log-tree-opt structure with rev-info structure
did not work out very well and it broke things that did not want
diff options and/or rev options.

This is an alternative approach to define a combined interface
that can be used by commands that wants both.  The use of it is
opt-in to reduce the risk of breaking existing programs.

Use less memory in "git log"

This trivially avoids keeping the commit message data around after we
don't need it any more, avoiding a continually growing "git log" memory
footprint.

It's not a huge deal, but it's somewhat noticeable. For the current kernel
tree, doing a full "git log" I got

ie the touched pages dropped from 8851 to 5039. For the historic kernel
archive, the numbers are 18357->11037 minor page faults.

We could/should in theory free the commits themselves, but that's really a
lot harder, since during revision traversal we may hit the same commit
twice through different children having it as a parent, even after we've
shown it once (when that happens, we'll silently ignore it next time, but
we still need the "struct commit" to know).

And as the commit message data is clearly the biggest part of the commit,
this is the really easy 60% solution.

Implement limited context matching in git-apply.

Ok this really should be the good version.  The option
handling has been reworked to be automation safe.

Currently to import the -mm tree I have to work around
git-apply by using patch.  Because some of Andrews
patches in quilt will only apply with fuzz.

I started out implementing a --fuzz option and then I realized
fuzz is not a very safe concept for an automated system.  What
you really want is a minimum number of context lines that must
match.  This allows policy to be set without knowing how many
lines of context a patch actually provides.   By default
the policy remains to match all provided lines of context.

Allowng git-apply to match a restricted set of context makes
it much easier to import the -mm tree into git.  I am still only
processing  1.5 to 1.6 patches a second for the 692 patches in
2.6.17-rc1-mm2 is still painful but it does help.

If I just loop through all of Andrews patches in order
and run git-apply --index -C1 I process the entire patchset
in 1m53s or about 6 patches per second.  So running
git-mailinfo, git-write-tree, git-commit-tree, and
git-update-ref everytime has a measurable impact,
and shows things can be speeded up even more.

All of these timings were taking on my poor 700Mhz Athlon
with 512MB of ram.  So people with fast machiens should
see much better performance.

When a match is found after the number of context are reduced a
warning is generated.  Since this is a rare event and possibly
dangerous this seems to make sense.  Unless you are patching
a single file the error message is a little bit terse at
the moment, but it should be easy to go back and fix.

I have also updated the documentation for git-apply to reflect
the new -C option that sets the minimum number of context
lines that must match.

Make "--parents" logs also be incremental

The parent rewriting feature caused us to create the whole history in one
go, and then simplify it later, because of how rewrite_parents() had been
written. However, with a little tweaking, it's perfectly possible to do
even that one incrementally.

Right now, this doesn't really much matter, because every user of
"--parents" will probably generally _also_ use "--topo-order", which will
cause the old non-incremental behaviour anyway. However, I'm hopeful that
we could make even the topological sort incremental, or at least
_partially_ so (for example, make it incremental up to the first merge).

blame: use built-in xdiff

This removes the last use of external diff from core git suite.
Also addresses the use of index() -- elsewhere we tend to use
strchr().

git-commit: document --amend

The "--amend" option is used to amend the tip of the current branch. This
documentation text was copied straight from the commit that implemented it.

Some minor format tweaks for asciidoc were taken from work by Francis Daly
in commit b0d08a5.. It looks good now also in the html page.

commit 3070b60].
