registrar: define revsetpredicate to decorate revset predicate

revsetpredicate is used to replace revset.predicate and
revset.extpredicate in subsequent patches.

This patch also adds loadpredicate() to revset, because this
combination helps to figure out how the name of safe predicate is put
into safesymbols.

This patch still uses safesymbols set to examine whether the predicate
corresponded to the 'name' is safe from DoS attack or not, because
just setting func._safe property needs changes below for such
examination.

  before:
      name in revset.safesymbols

  after:
      getattr(revset.symbols.get(name, None), '_safe', False)

"automatic registration" described in help doc of revsetpredicate
class will be achieved by the subsequent patch, which lists
loadpredicate() up in dispatch.extraloaders.
