phabricator: add a config to use curl for communication

Not sure why, but I got `phabsend` hang on work network pretty frequently.
The traceback indicates it hangs at `_sslobj.do_handshake()`:

  File "mercurial/sslutil.py", line 404, in wrapsocket
    sslsocket = sslcontext.wrap_socket(sock, server_hostname=serverhostname)
  File "/usr/lib/python2.7/ssl.py", line 363, in wrap_socket
    _context=self)
  File "/usr/lib/python2.7/ssl.py", line 611, in __init__
    self.do_handshake()
  File "/usr/lib/python2.7/ssl.py", line 840, in do_handshake
    self._sslobj.do_handshake()

I had tried adding `timeout` in various places but they seem not effective.
It seems easier to just allow shelling out to `curl` with retry and timeout
flags.

This could also be helpful for people with an older Python installed without
modern security (SNI).

# Dummy extension to define a namespace containing revision names

from __future__ import absolute_import

from mercurial import (
    namespaces,

def reposetup(ui, repo):
    names = {'r%d' % rev: repo[rev].node() for rev in repo}
    namemap = lambda r, name: names.get(name)
    nodemap = lambda r, node: ['r%d' % repo[node].rev()]

    ns = namespaces.namespace('revnames', templatename='revname',
                              logname='revname',
                              listnames=lambda r: names.keys(),
                              namemap=namemap, nodemap=nodemap)
    repo.names.addnamespace(ns)
