path-walk: add new 'edge_aggressive' option

Browse Source 
In preparation for allowing both the --shallow and --path-walk options
in the 'git pack-objects' builtin, create a new 'edge_aggressive' option
in the path-walk API. This option will help walk the boundary more
thoroughly and help avoid sending extra objects during fetches and
pushes.

The only use of the 'edge_hint_aggressive' option in the revision API is
within mark_edges_uninteresting(), which is usually called before
between prepare_revision_walk() and before visiting commits with
get_revision(). In prepare_revision_walk(), the UNINTERESTING commits
are walked until a boundary is found.
