revlog: ancestors(*revs) becomes ancestors(revs) (API)

Accepting a variable number of arguments as the old API did is
deeply ugly, particularly as it means the API can't be extended
with new arguments.  Partly as a result, we have at least three
different implementations of the same ancestors algorithm (!?).

Most callers were forced to call ancestors(*somelist), adding to
both inefficiency and ugliness.

  $ hg init

  $ touch to-be-deleted
  $ hg add
  adding to-be-deleted
  $ hg ci -m first
  $ echo a > to-be-deleted
  $ hg ci -m second
  $ rm to-be-deleted
  $ hg diff -r 0

Same issue, different code path

  $ hg up -C
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ touch doesnt-exist-in-1
  $ hg add
  adding doesnt-exist-in-1
  $ hg ci -m third
  $ rm doesnt-exist-in-1
  $ hg diff -r 1
