mq: new commands qselect, qguard

implement quilt-style guards for mq.

guards allow to control whether patch can be pushed.

if guard X is active and patch is guarded by +X (called "posative guard"),
patch can be pushed.  if patch is guarded by -X (called "nagative guard"),
patch cannot be pushed and is skipped.

use qguard to set/list guards on patches.  use qselect to set/list
active guards.

also "qseries -v" prints guarded patches with "G" now.
