obsolete: compute extinct changesets

`extinct` changesets are obsolete changesets with obsolete descendants only. They
are of no interest anymore and can be:

- exclude from exchange
- hidden to the user in most situation
- safely garbage collected

This changeset just allows mercurial to detect them.

The implementation is a bit naive, as for unstable changesets. We better use a
simple revset query and a cache, but simple version comes first.

  $ hg init a
  $ cd a
  $ hg init b
  $ echo x > b/x

Should print nothing:

  $ hg add b
  $ hg st

Should fail:

  $ hg st b/x
  abort: path 'b/x' is inside nested repo 'b' (glob)
  [255]
  $ hg add b/x
  abort: path 'b/x' is inside nested repo 'b' (glob)
  [255]

Should fail:

  $ hg add b b/x
  abort: path 'b/x' is inside nested repo 'b' (glob)
  [255]
  $ hg st

Should arguably print nothing:

  $ hg st b

  $ echo a > a
  $ hg ci -Ama a

Should fail:

  $ hg mv a b
  abort: path 'b/a' is inside nested repo 'b' (glob)
  [255]
  $ hg st

  $ cd ..
