templater: compute revset lazily This speeds up e.g. "{ifcontains(rev, revset('::.'), ...)}" in common cases where 'rev' is near the working parent. The templater API is ugly, but it helps here. 'f' can be either a generator or a function returning a generator.

mq may keep a reference to the repository so __del__ will not be
called and .hg/journal.dirstate will not be deleted:

  $ hg ci -m foo
  error: pretxncommit.nocommits hook failed: no commits allowed
  transaction abort!
  rollback completed
  abort: no commits allowed
  [255]
  $ hg ci -m foo
  error: pretxncommit.nocommits hook failed: no commits allowed

  rollback completed
  abort: no commits allowed
