Most of this change is to boilerplate commentary such as license URLs.
This change was prompted by ftp://ftp.gnu.org's going-away party,
planned for November. Change these FTP URLs to https://ftp.gnu.org
instead. Make similar changes for URLs to other organizations moving
away from FTP. Also, change HTTP to HTTPS for URLs to gnu.org and
fsf.org when this works, as this will further help defend against
man-in-the-middle attacks (for this part I omitted the MS-DOS and
MS-Windows sources and the test tarballs to keep the workload down).
HTTPS is not fully working to lists.gnu.org so I left those URLs alone
for now.

for the details.
* vc/vc-hooks.el (vc-state, vc-working-revision):
Use `vc-responsible-backend' in order to support unregistered files.
* vc/vc-rcs.el (vc-rcs-fetch-master-state):
* vc/vc-sccs.el (vc-sccs-working-revision): Handle undefined
master name.
* vc/vc-rcs.el (vc-rcs-unregister): Support unregistered files.
* vc/vc-src.el (vc-src-working-revision): Do not return an empty string.
* 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.
Alters vc/vc-bzr.el, vc/vc-cvs.el, vc/vc-dav.el, vc/vc-git.el,
vc/vc-hg.el, vc/vc-mtn.el, vc/vc-rcs.el, vc/vc-sccs.el,
vc/vc-svn.el, vc/vc.el.
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,
vc/vc-git.el, vc/vc-hg.el, vc/vc-mtn.el, vc/vc-rcs.el,
vc/vc-sccs.el, vc/vc-svn.el, vc/vc.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.
