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).

phabricator: standardize colors Previously, the `--confirm` text could have colors but the main `phabsend` does not. This patch adjusts the main command so it also has colors. A default color table was added so the colors are visible by default. Differential Revision: https://phab.mercurial-scm.org/D515

wireproto: do not abort after successful lookup As far as I can tell, this interface originally used 'return' here, so the "fallthrough" to self._abort made sense. When it was switched to 'yield' this didn't make sense, but doesn't impact most uses because the 'plain' wrapper in peer.py's 'batchable' decorator only attempts to yield two items (args and value). When using iterbatch, however, it attempts to verify that the @batchable generators only emit 2 results, by expecting a StopIteration when attempting to access a third.
