stablerange: move the subrange cache into our new class

This is the first step toward having more logic in that class

====================================
Testing head checking code: Case A-1
====================================

Mercurial checks for the introduction of multiple heads on push. Evolution
comes into play to detect if existing heads on the server are being replaced by
some of the new heads we push.

This test file is part of a series of tests checking this behavior.

Category A: checking simple case invoving a branch being superceeded by another.
TestCase 1: single-changeset branch
