bash_completion: completion for commands provided by extensions

Make the bash_completion function call _hg_cmd_$cmd to generate
completion candidates for $cmd if that function exists.

Add basic completion functions for:

- mq:
  - qpop
  - qpush
  - qdelete
  - qsave
  - qcommit
  - strip

- hbisect:
  - bisect

- patchbomb:
  - email

- gpg:
  - sign
