branch closing: add test for branch closing (and reopening)

branch closing: referencing open and closed branches/heads Treat fully closed branches similarly to "inactive" in the output of 'hg branches'. They will be suffixed with "(closed)" where inactive branches are marked with "(inactive)". If the -a/--active option is given both inactive and closed branches will not be shown. Partially closed branches (multiple heads, at least one not closed) will display the next (tipmost) open head. Add -a/--active option to "hg heads" which will hide closed heads iff the option is specified. In other hg commands, when multiple branch heads exist the branch name will refer to the tipmost open head, and if none exist, then the tipmost closed head.

branch closing: mark closed branches with a 'close' extra Adds a --close-branch option to commit. When --close-branch is present the commit will mark the changeset with close=1 in the changeset extras field. If a regular changeset is added on top of a closed head the branch is no longer considered closed, and thus re-opened.

store all heads of a branch in the branch cache All heads of branches will be stored in a new cache file 'branchheads.cache' within the .hg directory. The old 'branch.cache' file from older versions will be ignored. The new cache contents are formatted line-by-line as '{node} {branchtag}\n'. This is the same as the previous format. Now, every head is recorded in an oldest -> tipmost order. The localrepo.branchheads function is reworked to use the data from the cache.
