templates: fix ifcontains against sets with length > 1 (issue4259)

Previously the ifcontains revset was checking against the set using a pure
__contains__ check.  It turns out the set was actually a list of
formatted strings meant for ui output, which meant the contains check failed if
the formatted string wasn't significantly different from the raw value.

This change makes it check against the raw data, prior to it being formatted.

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.

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().

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.

bundle2: make sure standard stream are binary

Python on Windows apparently use encoded stream by default. We use the same
trick than elsewhere in the code to make them binary.

This should fix the current buildbot failure on windows.

alias: fix loss of non-zero return code in command aliases

This also includes test for shell aliases.  It avoid using "false" command
because "man false" does not say "exit with 1" but "exit with a status code
indicating failure."
