Marco Costalba reports that --remove-empty omits the commit that
created paths we are interested in. try_to_simplify_commit()
logic was dropping a parent we introduced those paths against,
which I think is not what we meant. Instead, this marks such
parent uninteresting. The traversal does not go beyond that
parent as advertised, but we still say that the current commit
changed things from that parent.

prune_fn in the rev_info structure is called in place of
try_to_simplify_commit. This makes it possible to do rename tracking
with a custom try_to_simplify_commit-like function.
This commit also introduces init_revisions which initialises the rev_info
structure with default values.

When git-rev-list (and git-log) collapsed ancestry chain to
commits that touch specified paths, we failed to inspect and
notice tree changes when we are about to hit uninteresting
parent. This resulted in "git rev-list since.. -- file" to
always show the child commit after the lower bound, even if it
does not touch the file. This commit fixes it.
Thanks for Catalin for reporting this.

revision.c:make_parents_uninteresting() is exponential with the number
of merges in the tree. That's fine -- unless some other part of git
already has pulled the whole commit tree into memory ...

This moves the handling of max-count shorthand from the internal
implementation of "git log" to setup_revisions() so other users
of setup_revisions() can use it.

Well, assuming breaking --merge-order is fine, here's a patch (on top of
the other ones) that makes
git log <filename>
actually work, as far as I can tell.
I didn't add the logic for --before/--after flags, but that should be
pretty trivial, and is independent of this anyway.

This actually moves the "meat" of the revision walking from rev-list.c
to the new library code in revision.h. It introduces the new functions
void prepare_revision_walk(struct rev_info *revs);
struct commit *get_revision(struct rev_info *revs);
to prepare and then walk the revisions that we have.

This makes the rewrite easier to validate in that revision flag
parsing and warlking part are now all in rev_info structure.

This really just splits things up partially, and creates the
interface to set things up by parsing the command line.
No real code changes so far, although the parsing of filenames is a bit
stricter. In particular, if there is a "--", then we do not accept any
filenames before it, and if there isn't any "--", then we check that _all_
paths listed are valid, not just the first one.
The new argument parsing automatically also gives us "--default" and
"--not" handling as in git-rev-parse.
