merge: use separate lists for each action type This replaces the grand unified action list that had multiple action types as tuples in one big list. That list was iterated multiple times just to find actions of a specific type. This data model also made some code more convoluted than necessary. Instead we now store actions as a tuple of lists. Using multiple lists gives a bit of cut'n'pasted code but also enables other optimizations. This patch uses 'if True:' to preserve indentations and help reviewing. It also limits the number of conflicts with other pending patches. It can trivially be cleaned up later.

changelog: ensure changelog._delaybuf is initialized The ``localrepo.writepending`` method is using the ``changelog._delaybuff`` attribute to know if it has anything to do. However the ``changelog._delaybuff`` is never initialised at ``__init__`` time. This can lead to crash when using bundle2 for part that never touch the changelog. We simply initialize it to its base value. This is scheduled for stable as it both trivial and blocking for experimenting with bundle2.

proxy: remove unneeded _set_hostport for compatibility with Python 2.7.7rc1 With Python 2.7.7rc1, "hg pull" through HTTP CONNECT tunnel fails due to the removal of _set_hostport [1]. ... File "mercurial/url.py", line 372, in https_open return self.do_open(self._makeconnection, req) ... File "mercurial/url.py", line 342, in connect _generic_proxytunnel(self) File "mercurial/url.py", line 228, in _generic_proxytunnel self._set_hostport(self.host, self.port) AttributeError: httpsconnection instance has no attribute '_set_hostport' self._set_hostport(self.host, self.port) should be noop and can be removed because: - _set_hostport() [2] was the function to parse "host:port" string and set them to self.host and self.port, - and (self.host, self.port) pair should be valid since connect() is called prior to _generic_proxytunnel().

bugzilla: support Bugzilla 4.4.3+ API login token authentication (issue4257) Bugzilla 4.4.3 and later remove the old cookie based session authentication from the Web Services API and replace it with a login token. The session can now also be restricted to the originating IP. Add the necessary to the extension so it works with 4.4.3 and later.
