This adds Linus's wish, "--merge" flag, which makes the above
expand to a rough equivalent to:

Fix clear_commit_marks() enough to be usable in

Signed-off-by: NJunio C Hamano <junkio@cox.net>

This makes git-peek-remote able to basically do everything that
git-ls-remote does (but obviously just for the native protocol, so no
http[s]: or rsync: support).

The default behaviour is the same, but you can now give a mixture of
"--refs", "--tags" and "--heads" flags, where "--refs" forces
git-peek-remote to only show real refs (ie none of the fakey tag lookups,
but also not the special pseudo-refs like HEAD and MERGE_HEAD).

The "--tags" and "--heads" flags respectively limit the output to just
regular tags and heads, of course.

You can still also ask to limit them by name too.

You can combine the flags, so

	git peek-remote --refs --tags .

will show all local _true_ tags, without the generated tag lookups
(compare the output without the "--refs" flag).

And "--tags --heads" will show both tags and heads, but will avoid (for
example) any special refs outside of the standard locations.

I'm also planning on adding a "--ignore-local" flag that allows us to ask
it to ignore any refs that we already have in the local tree, but that's
an independent thing.

All this is obviously gearing up to making "git fetch" cheaper.

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.

This is to pull in the object-hash clean-up from the master branch.

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.
