phase: use a binary phase part to push through bundle2 (BC)

The part we are using for pull is now used for push too. As we no longer use
pushkey, pushkey hooks are no longer triggered. This is an obvious backward
incompatible change. We could artificially trigger the pushkey hook within the
bundle2 part, but this seemed too hacky to me.

An option would be to disable by default this new mechanism for a couple of
versions to help people migrate to `txnclose-phase`. I took the liberal and
optimistic path to just turn it on by default directly.

.. bc::

   Push no longer triggers a pushkey hook when updating phases. Use the new
   `txnclose-phase` and `txnclose-phase` hooks instead.
   (Applies when both server and client use version 4.4 or above).

     Bundle specifications denote a well-defined bundle/exchange format.
     The content of a given specification should not change over time in
     order to ensure that bundles produced by a newer version of Mercurial are
     readable from an older version.
 
     The string currently has the form:
 
        <compression>-<type>[;<parameter0>[;<parameter1>]]
 
     Where <compression> is one of the supported compression formats
     and <type> is (currently) a version string. A ";" can follow the type and
     all text afterwards is interpreted as URI encoded, ";" delimited key=value
     pairs.
 
     If ``strict`` is True (the default) <compression> is required. Otherwise,
     it is optional.
 
     If ``externalnames`` is False (the default), the human-centric names will
     be converted to their internal representation.

     be ``None`` if not in strict mode and a compression isn't defined.

     not syntactically well formed.
