revlog: always process opener options
I'm not sure when ``opener.options`` would ever be explicitly
set to None. It is definitely not possible to construct a repo
this way because ``localrepo.resolvestorevfsoptions()`` always
returns a dict and ``localrepo.makelocalrepository()`` always
sets ``opener.options`` to this value.
Because we always execute this code now, if options are empty
we defaulted to creating version 0 revlogs. So we had to change
the code slightly to fall back to the default revlog version
and flags.
As astute reader will note that it is not possible to create
version 0 revlogs now. However, I don't think it was possible
before, as this required ``opener.options`` being unset, which
I don't think was possible. I suspect this means our test
coverage for version 0 revlog repositories is possibly
non-existent! Since I don't see a config option to disable
revlog v1, I'm not even sure if we had a way to create new
repos with version 0 revlogs! Who knows.
