revwalked in the same way as git.

merge: reverse merge bases for recursive merge
When the commits being merged have multiple merge bases, reverse the
order when creating the virtual merge base. This is for compatibility
with git's merge-recursive algorithm, and ensures that we build
identical trees.
Git does this to try to use older merge bases first. Per 8918b0c:
> It seems to be the only sane way to do it: when a two-head merge is
> done, and the merge-base and one of the two branches agree, the
> merge assumes that the other branch has something new.
>
> If we start creating virtual commits from newer merge-bases, and go
> back to older merge-bases, and then merge with newer commits again,
> chances are that a patch is lost, _because_ the merge-base and the
> head agree on it. Unlikely, yes, but it happened to me.

merge: virtual commit should be last argument to merge-base
Our virtual commit must be the last argument to merge-base: since our
algorithm pushes _both_ parents of the virtual commit, it needs to be
the last argument, since merge-base:
> Given three commits A, B and C, git merge-base A B C will compute the
> merge base between A and a hypothetical commit M
We want to calculate the merge base between the actual commit ("two")
and the virtual commit ("one") - since one actually pushes its parents
to the merge-base calculation, we need to calculate the merge base of
"two" and the parents of one.

merge: handle conflicts in recursive base building
When building a recursive merge base, allow conflicts to occur.
Use the file (with conflict markers) as the common ancestor.
The user has already seen and dealt with this conflict by virtue
of having a criss-cross merge. If they resolved this conflict
identically in both branches, then there will be no conflict in the
result. This is the best case scenario.
If they did not resolve the conflict identically in the two branches,
then we will generate a new conflict. If the user is simply using
standard conflict output then the results will be fairly sensible.
But if the user is using a mergetool or using diff3 output, then the
common ancestor will be a conflict file (itself with diff3 output,
haha!). This is quite terrible, but it matches git's behavior.

introduce `git_index_entry_is_conflict`
It's not always obvious the mapping between stage level and
conflict-ness. More importantly, this can lead otherwise sane
people to write constructs like `if (!git_index_entry_stage(entry))`,
which (while technically correct) is unreadable.
Provide a nice method to help avoid such messy thinking.

Remove the "merge none" flag
The "merge none" (don't automerge) flag was only to aide in
merge trivial tests. We can easily determine whether merge
trivial resulted in a trivial merge or an automerge by examining
the REUC after automerge has completed.

merge_file should use more aggressive levels
The default merge_file level was XDL_MERGE_MINIMAL, which will
produce conflicts where there should not be in the case where
both sides were changed identically. Change the defaults to be
more aggressive (XDL_MERGE_ZEALOUS) which will more aggressively
compress non-conflicts. This matches git.git's defaults.
Increase testing around reverting a previously reverted commit to
illustrate this problem.
