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

     - It prevents the use of a repo with multiple filters at the same time. In
       particular when multiple threads are involved.
     - It makes scope of the filtering harder to control.
 
     This object behaves very closely to the original repository. All attribute
     operations are done on the original repository:
     - An access to `repoview.someattr` actually returns `repo.someattr`,
     - A write to `repoview.someattr` actually sets value of `repo.someattr`,
     - A deletion of `repoview.someattr` actually drops `someattr`
       from `repo.__dict__`.
 
     The only exception is the `changelog` property. It is overridden to return
     a (surface) copy of `repo.changelog` with some revisions filtered. The
     `filtername` attribute of the view control the revisions that need to be
     filtered.  (the fact the changelog is copied is an implementation detail).
 
     Unlike attributes, this object intercepts all method calls. This means that
     all methods are run on the `repoview` object with the filtered `changelog`
     property. For this purpose the simple `repoview` class must be mixed with
     the actual class of the repository. This ensures that the resulting
     `repoview` object have the very same methods than the repo object. This
     leads to the property below.
 
         repoview.method() --> repo.__class__.method(repoview)
 
     The inheritance has to be done dynamically because `repo` can be of any
     subclasses of `localrepo`. Eg: `bundlerepo` or `httprepo`.

         # Handle locally computable results first:
         if not one:

         # request now. Decode it:

     method, but adds the original method as an attribute called "batchable",

 |Note:
 |
 | After the last rollback, the "unserved" branchheads cache became invalid, but
 | all changesets in the repo were public. For filtering this means:
 |   "mutable" == "unserved" == ø.
 |
 | As the "unserved" cache is invalid, we fall back to the "mutable" cache. But
 | no update is needed between "mutable" and "unserved" and the "unserved" cache
 | is not updated on disk. The on-disk version therefore stays invalid for some
 | time. This explains why the "unserved" branchheads cache is detected as
 | invalid here.
