ancestor: add lazy membership testing to lazyancestors

This also makes the perfancestorset command use lazy membership testing. In a
linear repository with over 400,000 commits, without this patch, hg
perfancestorset takes 0.80 seconds no matter how far behind we're looking.
With this patch, hg perfancestorset -- X takes:

    Rev X       Time
       -1      0.00s
    -4000      0.01s
   -20000      0.04s
   -80000      0.17s
  -200000      0.43s
  -300000      0.69s
        0      0.88s

Thus, for revisions close to tip, we're up to several orders of magnitude
faster. At 0 we're around 10% slower.
