revset: replace extpredicate by revsetpredicate of registrar

This patch consists of changes below (these can't be applied
separately).

  - replace revset.extpredicate by registrar.revsetpredicate in
    extensions

  - remove setup() on an instance named as revsetpredicate in
    uisetup()/extsetup() of each extensions

    registrar.revsetpredicate doesn't have setup() API.

  - put new entry for revsetpredicate into extraloaders in dispatch

    This causes implicit loading predicate functions at loading
    extension.

    This loading mechanism requires that an extension has an instance
    named as revsetpredicate, and this is reason why
    largefiles/__init__.py is also changed in this patch.

Before this patch, test-revset.t tests that all decorated revset
predicates are loaded by explicit setup() at once ("all or nothing").

Now, test-revset.t tests that any revset predicate isn't loaded at
failure of loading extension, because loading itself is executed by
dispatch and it can't be controlled on extension side.
