localrepo: move some vfs initialization out of __init__
In order to make repository types more dynamic, we'll need to move the
logic for determining repository behavior out of
localrepository.__init__ so we can influence behavior before the type
is instantiated.
This commit starts that process by moving working directory and .hg/
vfs initialization to our new standalone function for instantiating
local repositories.
Aside from API changes, behavior should be fully backwards compatible.
.. api::
localrepository.__init__ now does less work and accepts new args
Use ``hg.repository()``, ``localrepo.instance()``, or
``localrepo.makelocalrepository()`` to obtain a new local repository
instance instead of calling the ``localrepository`` constructor
directly.
