Use `vc-responsible-backend' in order to support unregistered files.

* vc/vc.el, vc/vc-hg.el, vc/vc-git.el, vc/vc-hooks.el,
vc/vc-mtn.el, vc/vc-rcs.el, vc/vc-sccs.el, vc/vc-src.el: rrollback
method removed, to be replaced in the future by uncommit.
* vc/vc-cvs.el, vc/vc-hooks.el, vc/vc-rcs.el, vc/vc-sccs.el: Eliminate
vc-mistrust-permissions. It was only relevant to the RCS and SCCS
back ends and defaulted to t. Code now always mistrusts permissions -
by actual measurement the effect on performance is negligible. As a
side effect bug#11490 is now irrelevant.
* vc/vc.el, vc-hooks.el, and all backends: API simplification;
vc-workfile-unchanged-p is no longer a public method (but the RCS and
SCCS back ends retain it as a private method used in state
computation). This method was redundant with vc-state and usually
implemented as a trivial call to same. Fixes the failure mode
described in bug#694.
This hasn't made any sense since RCS, and was a dumb stunt then.
* vc/vc.el and all backends: API simplification; init-revision is
gone, and vc-registered functions no longer take an initial-revision
argument.
* vc-hooks.el, vc-rcs.el, vc-sccs.el: vc-name -> vc-master-name. This
is preaparatory to isolating all the 'master' functions used only by
the file-oriented back ends. With this done first, the substantive
diffs will be easier to read.

where this matters (which is only in SCCS and RCS) files are now always
checked out editable. This may actually have been dynamically true
already - it looks like the vc-next-action code evolved past visiting
the other case. Tested with RCS.
Alters vc/vc-arch.el, vc/vc-bzr.el, vc/vc-cvs.el, vc/vc-dav.el,

Only the RCS, SCCS, and CVS back ends tried to do anything with it,
and that code was never exercised. Chiseling away the cruft of
decades...
* lisp/vc/vc-sccs.el (vc-sccs-registered): Use the progn trick to get
the full definition in loaddefs, rather than duplicating it.
Cf vc-rcs-registered.
* lisp/vc/vc-sccs.el (vc-sccs-write-revision): New function.
(vc-sccs-workfile-unchanged-p): Use vc-sccs-write-revision.
(vc-sccs-diff): Replace use of the external vcdiff script.
