tests: add glob matching for unified tests

This adds a " (glob)" marker that works like a simpler version of
(re): "*" is converted to ".*", and "?" is converted to ".".

Both special characters can be escaped using "\", and the backslash
itself can be escaped as well.

Other glob-style syntax, like "**", "[chars]", or "[!chars]", isn't
supported.

  $ hg init repo
  $ cd repo

  $ touch foo bar
  $ hg ci -Am 'add foo bar'
  adding bar
  adding foo

  $ touch baz
  $ hg add baz
  $ hg rm bar

  $ hg debugrebuildstate

state dump after

  $ hg debugstate --nodates | sort
  n 666         -1 bar
  n 666         -1 foo

status

  $ hg st -A
  ! bar
  ? baz
  C foo
