Common option parsing for "git log --diff" and friends

This basically does a few things that are sadly somewhat interdependent,
and nontrivial to split out

 - get rid of "struct log_tree_opt"

   The fields in "log_tree_opt" are moved into "struct rev_info", and all
   users of log_tree_opt are changed to use the rev_info struct instead.

 - add the parsing for the log_tree_opt arguments to "setup_revision()"

 - make setup_revision set a flag (revs->diff) if the diff-related
   arguments were used. This allows "git log" to decide whether it wants
   to show diffs or not.

 - make setup_revision() also initialize the diffopt part of rev_info
   (which we had from before, but we just didn't initialize it)

 - make setup_revision() do all the "finishing touches" on it all (it will
   do the proper flag combination logic, and call "diff_setup_done()")

Now, that was the easy and straightforward part.

The slightly more involved part is that some of the programs that want to
use the new-and-improved rev_info parsing don't actually want _commits_,
they may want tree'ish arguments instead. That meant that I had to change
setup_revision() to parse the arguments not into the "revs->commits" list,
but into the "revs->pending_objects" list.

Then, when we do "prepare_revision_walk()", we walk that list, and create
the sorted commit list from there.

This actually cleaned some stuff up, but it's the less obvious part of the
patch, and re-organized the "revision.c" logic somewhat. It actually paves
the way for splitting argument parsing _entirely_ out of "revision.c",
since now the argument parsing really is totally independent of the commit
walking: that didn't use to be true, since there was lots of overlap with
get_commit_reference() handling etc, now the _only_ overlap is the shared
(and trivial) "add_pending_object()" thing.

However, I didn't do that file split, just because I wanted the diff
itself to be smaller, and show the actual changes more clearly. If this
gets accepted, I'll do further cleanups then - that includes the file
split, but also using the new infrastructure to do a nicer "git diff" etc.

Even in this form, it actually ends up removing more lines than it adds.

It's nice to note how simple and straightforward this makes the built-in
"git log" command, even though it continues to support all the diff flags
too. It doesn't get much simpler that this.

I think this is worth merging soonish, because it does allow for future
cleanup and even more sharing of code. However, it obviously touches
"revision.c", which is subtle. I've tested that it passes all the tests we
have, and it passes my "looks sane" detector, but somebody else should
also give it a good look-over.

if something like the following would help people converting a
huge repository from foreign SCM, or preparing a repository to
be fetched over plain dumb HTTP only:

        #!/bin/sh

        N=4
        P=.git/objects/pack
        bottom=

        while test 0 \< $N
        do
                N=$((N-1))
                if test -z "$bottom"
                then
                        newbottom=`git rev-list --bisect --all`
                else
                        newbottom=`git rev-list --bisect ^$bottom --all`
                fi
                if test -z "$bottom"
                then
                        rev_list="$newbottom"
                elif test 0 = $N
                then
                        rev_list="^$bottom --all"
                else
                        rev_list="^$bottom $newbottom"

                p=$(git rev-list --unpacked --objects $rev_list |
                    git pack-objects $P/pack)
                git show-index <$P/pack-$p.idx | wc -l
                bottom=$newbottom
        done

The idea is to pack older half of the history to one pack, then
older half of the remaining history to another, to continue a
few times, using finer granularity as we get closer to the tip.

This may not matter, since for a truly huge history, running
bisect number of times could be quite time consuming, and we
might be better off running "git rev-list --all" once into a
temporary file, and manually pick cut-off points from the
resulting list of commits.  After all we are talking about
"approximately half" for such an usage, and older history does
not matter much.

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.

tree-diff: do not assume we use only one pathspec

The way tree-diff was set up assumed we would use only one set
of pathspec during the entire life of the program.  Move the
pathspec related static variables out to diff_options structure
so that we can filter commits with one set of paths while show
the actual diffs using different set of paths.

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).

In the meantime, this at least moves things in the right direction, and
removes a strange special case.

xdiff/xdiffi.c: fix warnings about possibly uninitialized variables

Compiling this module gave the following warnings (some double dutch!):

xdiff/xdiffi.c: In functie 'xdl_recs_cmp':
xdiff/xdiffi.c:298: let op: 'spl.i1' may be used uninitialized in this function

A superficial tracking of their usage, without deeper knowledge about the
algorithm, indeed confirms that there are code paths on which these
variables will be used uninitialized. In practice these code paths might never
be reached, but then these fixes will not change the algorithm. If these
code paths are ever reached we now at least have a predictable outcome. And
should the very small performance impact of these initializations be
noticeable, then they should at least be replaced by comments why certain
code paths will never be reached.

Some extra initializations in this patch now fix the warnings.
