phases: avoid N² behavior in `advanceboundary`
We allowed duplicated entries in the deque, which each entry could potentially
insert all its ancestors. So advancing boundary for the full repository would
mean each revision would walk all its ancestors, resulting in O(N²) iteration.
For repository of any decent size, N² is quickly insane.
We introduce a simple set to avoid this and get back to reasonable performance.

==================================== Testing head checking code: Case E-1 ==================================== Mercurial checks for the introduction of new heads on push. Evolution comes into play to detect if existing branches on the server are being replaced by some of the new one we push. This case is part of a series of tests checking this behavior. Category E: case involving changeset on multiple branch TestCase 8: moving a branch to another location .. old-state: .. .. * 1-changeset on branch default .. * 1-changeset on branch Z (above default) .. .. new-state: .. .. * 1-changeset on branch default .. * 1-changeset on branch Z (rebased away from A0) .. .. expected-result: .. .. * push allowed .. .. graph-summary: .. ..
