convert: better support for CVS branchpoints (issue1447)

This records the branches starting at individual CVS file revisions,
using the symbolic names map rather than just the branches
information.  This information is used to generate Mercurial
changesets. Despite the changes, the CVS conversion still suffers
heavily from cvsps' deficiencies in generating a correct
representation of the CVS repository history.

# The converter does not currently handle patch conflicts very well.
# When they occur, it reverts *all* changes and moves forward,
# letting the conflict resolving patch fix collisions.
# Unfortunately, non-conflicting changes, like the addition of the
# "c" file in p1.1 patch are reverted too.
# Just to say that manifest not listing "c" here is a bug.
