[PATCHv3 0/4] git p4: label import/export

This is a reworked version of my earlier patches for adding
improved label import/export support to "git p4", and
incorporates comments from Pete Wyckoff and Junio:

Comments from Pete:

* The verbose flag has been hoisted to the Command class.
* Uses the existing functions to fish out p4 changelist numbers.
* Config options renamed to be self-consistent, and regexp
  now includes lower-case characters.

I have left the tests in t9811 where they are, so that the t9804
script can be used solely for "--detect-labels".

Comments from Junio:

* P4EDITOR is set to the always-true value in the test harness
* Treat an empty P4EDITOR the same as an unset P4EDITOR.

There was a discussion about having "git p4" fall back to a default in
the same way that "p4" does, but this would change the existing behavior
(use git var GIT_EDITOR) and confuse users.

This patch series was reworked against ld/git-p4-tags-and-labels and
also has a very small documentation fix.
