performance: speedup computation of unserved revisions In their current state, revset calls can be very costly, as we test predicates on the entire repository. The "unserved" filter is used in multiple applications, and in particular in some branch cache loading operations. We need to make it fast. This change drops revset calls in favor of direct testing of the phase of a changeset. Performance test on my Mercurial checkout - 19857 total changesets, - 1584 obsolete changesets, - 13310 obsolescence markers.

performance: speedup computation of hidden revisions In their current state, revset calls can be very costlys, as we test predicates on the entire repository. The hidden filter is very widely used, and needs to be very fast. This change drops revset calls in favor of direct revision manipulation. Performance test on my Mercurial checkout - 19857 total changesets, - 1584 obsolete changesets, - 13310 obsolescence markers.

performance: speedup computation of obsolete revisions In their current state, revset calls can be very costly as we test predicates on the entire repository. As obsolete computation is used by the "hidden" filter, it needs to be very fast. This changet drops the revset call in favor of direct testing of the phase of a changeset.

clfilter: drop unnecessary explicit filtering on histedit Hidden changeset filtering is now done at repo level. The orphaned children computation will not include any (unless you add --hidden).

clfilter: drop unnecessary explicit filtering on rebase Hidden changeset filtering is now done at repo level. The rebaseset computation will not include any (unless you add --hidden).

clfilter: ensure that hidden filtering is working on all commands Now that hidden changeset are filtered for all commands, we test the behavior of `heads` and `summary` regarding hidden changeset.

clfilter: enforce hidden changeset globally The dispatch code now enables filtering of "hidden" changesets globally. The filter is installed before command and extension invocation. The `--hidden` switch is now global and disables this filtering for any command. Code in log dedicated to changeset exclusion is removed as this global filtering has the same effect.

record: use patch.diffopts to account for user diffopts This allows user defined diff options (e.g. showfunc) to be accounted for when using record. A test has been updated accordingly.
