manifest: use a size 3 LRU cache to store parsed manifests

Previously, the manifest cache would store the last manifest parsed. We could
run into situations with operations like update where we would try parsing the
manifest for a revision r1, then r2, then r1 again. This increases the cache
size to 3 to avoid that bit of performance fragility.

  $ "$TESTDIR/hghave" execbit || exit 80

  $ rm -rf a
  $ hg init a
  $ cd a

  $ echo foo > foo
  $ hg ci -qAm0
  $ chmod +x foo
  $ hg ci -m1
  $ hg co -q 0
  $ echo dirty > foo
