performance: speedup computation of hidden revisions

In their current state, revset calls can be very costlys, as we
test predicates on the entire repository. The hidden filter is very
widely used, and needs to be very fast.

This change drops revset calls in favor of direct revision manipulation.

Case-changing renames should work:

  $ hg mv a A
  $ hg mv A a
  $ hg st

test changing case of path components

  $ mkdir D

on linux hfs keeps the old case stored, force it

  $ mv a aa
  $ mv aa A
  $ hg ci -Am addA
  adding A
