notify: support revset selection for subscriptions

A repo pattern for any notify configuration contains a glob matching the
path to the repo. Additionally, it may now contain a revset spec, separated
from the glob by '#'.

Example:
  [reposubs]
  */widgets#branch(release) = [e-mail]

This sends to ``[e-mail]`` whenever a changeset on the ``release``
branch triggers a notification in any repository ending in ``widgets``.

This patch was completely done by David Champion <[e-mail]> with me
making tiny changes to his tests.

    (dir, basename) = os.path.split(file._tempname)
