filtering: rename filters to their antonyms

Now that changelog filtering is in place, it's become evident that
naming the filters according to the set of revs _not_ included in the
filtered changelog is confusing. This is especially evident in the
collaborative branch cache scheme.

This changes the names of the filters to reflect the revs that _are_
included:

  hidden -> visible
  unserved -> served
  mutable -> immutable
  impactable -> base

repoview.filteredrevs is renamed to filterrevs, so that callers read a
bit more sensibly, e.g.:

  filterrevs('visible') # filter revs according to what's visible
