fileset: perform membership test against set for status queries
Previously, fileset functions operating on status items performed
membership tests against a list of items. When there are thousands
of items having a specific status, that test can be extremely
slow. Changing the membership test to a set makes this operation
substantially faster.
On the mozilla-central repo:
$ hg files -r d14cac631ecc 'set:added()'
before: 28.120s
after: 0.860s
$ hg status --change d14cac631ecc --added
0.690s
