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.

Try to call --continue:

  $ hg rebase --continue
  abort: no rebase in progress

Conflicting rebase:

  $ hg rebase -s 3 -d 2
  merging common
  warning: conflicts during merge.
  merging common incomplete! (edit conflicts, then use 'hg resolve --mark')
  abort: unresolved conflicts (see hg resolve, then hg rebase --continue)
  [255]

Try to continue without solving the conflict:

  $ hg rebase --continue
  abort: unresolved merge conflicts (see hg help resolve)
  [255]

Conclude rebase:

  $ echo 'resolved merge' >common
  $ hg resolve -m common
  $ hg rebase --continue
