revset.bisect: add new 'untested' set to the bisect keyword

The 'untested' set is made of changesets that are in the bisection range
but for which the status is still unknown, and that can later be used to
further decide on the bisection outcome.

Setup:

create a little extension that has 3 side-effects:
1) ensure changelog data is not inlined
2) make revlog to use lazyparser
3) test that repo.lookup() works
1 and 2 are preconditions for the bug; 3 is the bug.

Test that new changesets are visible to repo.lookup():

  $ echo a >> a
  $ hg commit -m'one more commit to demonstrate the bug'
  new tip: 799ae3599e0e

  $ hg tip
