performance: speedup computation of mutable revisions
In their current state, revset calls can be very costly, as we test
predicates on the entire repository. The "mutable" filter is used
during branch cache loading operation. We need to make it fast.
This change drops revset calls in favor of direct testing of the
phase of a changeset.

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: 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: 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).
