brian m. carlson 1684c1b219 rev-list: add an option to mark fewer edges as uninteresting
In commit fbd4a70 (list-objects: mark more commits as edges in
mark_edges_uninteresting - 2013-08-16), we marked an increasing number
of edges uninteresting.  This change, and the subsequent change to make
this conditional on --objects-edge, are used by --thin to make much
smaller packs for shallow clones.

Unfortunately, they cause a significant performance regression when
pushing non-shallow clones with lots of refs (23.322 seconds vs.
4.785 seconds with 22400 refs).  Add an option to git rev-list,
--objects-edge-aggressive, that preserves this more aggressive behavior,
while leaving --objects-edge to provide more performant behavior.
Preserve the current behavior for the moment by using the aggressive
option.

DESCRIPTION
-----------
List commits that are reachable by following the `parent` links from the
given commit(s), but exclude commits that are reachable from the one(s)
given with a '{caret}' in front of them. The output is given in reverse
chronological order by default.
You can think of this as a set operation. Commits given on the command
line form a set of commits that are reachable from any of them, and then
commits reachable from any of the ones given with '{caret}' in front are
subtracted from that set. The remaining commits are what comes out in the
command's output. Various other options and paths parameters can be used
to further limit the result.
Thus, the following command:
-----------------------------------------------------------------------
$ git rev-list foo bar ^baz
-----------------------------------------------------------------------
means "list all the commits which are reachable from 'foo' or 'bar', but
not from 'baz'".
A special notation "'<commit1>'..'<commit2>'" can be used as a
short-hand for "{caret}'<commit1>' '<commit2>'". For example, either of
the following may be used interchangeably:
-----------------------------------------------------------------------
$ git rev-list origin..HEAD
$ git rev-list HEAD ^origin
-----------------------------------------------------------------------
Another special notation is "'<commit1>'...'<commit2>'" which is useful
for merges. The resulting set of commits is the symmetric difference
between the two operands. The following two commands are equivalent:
-----------------------------------------------------------------------
$ git rev-list A B --not $(git merge-base --all A B)
$ git rev-list A...B
-----------------------------------------------------------------------
'rev-list' is a very essential Git command, since it
provides the ability to build and traverse commit ancestry graphs. For
this reason, it has a lot of different options that enables it to be
used by commands as different as 'git bisect' and
'git repack'.
