phases: make advance/retractboundary() atomic
Before this, if advanceboundary() failed after updating some roots but
before calling retractboundary(), the phase cache would be left in an
invalid state, marked dirty, and written as such. This patch approach is
to turn advance/retractboundary() into phasecache methods, then operate
on copies and merge them back on success.
With the same technique, we can ensure the atomicity of combinations of
advance/retractboundary() calls, like those performed in changegroup
handling code.
