branchmap: enable caching for filtered version too

The `_branchcache` attribute is turned into a dictionary. Key are filter name and
value is a `branchcache` object. Unfiltered version is cached as `None` filter.

The attribute is renamed to `_branchcaches` to avoid confusion with the previous
one. Both old and new contents are dictionary even if their contents are
different. I prefer possible extension code to crash right away instead of just
messing the wrong dictionary.

As all different caches work isolated to each other, this code keeps the
previous behavior of using the unfiltered cache  we nothing is filtered.  This
is a cheap way to have cache collaborate and nullify potential impact in the
default case.
