phabricator: add commenting to phabsend for new/updated Diffs

Especially useful when sending updates to existing Revisions so one can specify
the sort of changes e.g. "Address review comments" or "Rebase to tip"

If the diff content hasn't changed then it only needs a metadata update which
doesn't show in the Phabricator updates UI, so don't add a comment that will.

 """simple Phabricator integration (EXPERIMENTAL)
 
 This extension provides a ``phabsend`` command which sends a stack of
 changesets to Phabricator, and a ``phabread`` command which prints a stack of
 revisions in a format suitable for :hg:`import`, and a ``phabupdate`` command
 to update statuses in batch.
 
 By default, Phabricator requires ``Test Plan`` which might prevent some
 changeset from being sent. The requirement could be disabled by changing
 ``differential.require-test-plan-field`` config server side.
 
 Config::
 
     [phabricator]
     # Phabricator URL
     url = https://phab.example.com/
 
     # Repo callsign. If a repo has a URL https://$HOST/diffusion/FOO, then its
     # callsign is "FOO".
     callsign = FOO
 
     # curl command to use. If not set (default), use builtin HTTP library to
     # communicate. If set, use the specified curl command. This could be useful
     # if you need to specify advanced options that is not easily supported by
     # the internal library.

     could be used to filter patches by status. For performance reason, they
     only represent a subset of non-status selections and cannot be used alone.
 
     For example, ``:D6+8-(2+D4)`` selects a stack up to D6, plus D8 and exclude
     D2 and D4. ``:D9 & needsreview`` selects "Needs Review" revisions in a
     stack up to D9.
 
     If --stack is given, follow dependencies information and read all patches.
     It is equivalent to the ``:`` operator.

 Error is handled reasonably. We override the phabtoken here so that
 when you're developing changes to phabricator.py you can edit the
 above config and have a real token in the test but not have to edit
 this test.

   exchangev2: start to implement pull with wire protocol v2
   
   Wire protocol version 2 will take a substantially different
   approach to exchange than version 1 (at least as far as pulling
   is concerned).
   
   This commit establishes a new exchangev2 module for holding
 
 phabupdate with an accept:
   $ hg phabupdate --accept D4564 \
   > -m 'I think I like where this is headed. Will read rest of series later.'\
