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) = qa-team@example.com
This sends to ``qa-team@example.com`` whenever a changeset on the ``release``
branch triggers a notification in any repository ending in ``widgets``.
This patch was completely done by David Champion <dgc@uchicago.edu> with me
making tiny changes to his tests.
