revset: split language services to revsetlang module (API)

New revsetlang module hosts parser, tokenizer, and miscellaneous functions
working on parsed tree. It does not include functions for evaluation such as
getset() and match().

  2288 mercurial/revset.py
   684 mercurial/revsetlang.py
  2972 total

get*() functions are aliased since they are common in revset.py.
