* lisp/frameset.el: Add new predicate values for frameset-restore args.
(frameset-live-filter-alist, frameset-persistent-filter-alist):
New variables.
(frameset-filter-alist): Use them. Add autoload cookie.
(frameset-filter-tty-to-GUI): Move from desktop.el and rename.
(frameset--set-id, frameset--reuse-frame): Rename `frame-id' to
`frameset--id' (it's supposed to be internal to frameset.el).
(frameset--process-minibuffer-frames): Ditto. Doc fix.
(frameset--initial-params): New function.
(frameset--get-frame): Use it. Doc fix.
(frameset--move-onscreen): Accept new PRED value for FORCE-ONSCREEN.
Accept :all, not 'all.
(frameset-restore): Add new predicate values for FORCE-ONSCREEN and
FORCE-DISPLAY. Use :keywords for constant arguments to avoid collision
with fbound symbols. Fix frame id matching, and remove matching ids if
the frame being restored is deleted. Obey :delete.
* lisp/desktop.el (desktop-restore-forces-onscreen)
(desktop-restore-reuses-frames): Document :keyword constant values.
(desktop-filter-parameters-alist): Remove, now identical to
frameset-filter-alist.
(desktop--filter-tty*): Remove, moved to frameset.el.
(desktop-save-frameset, desktop-restore-frameset):
Do not pass :filters argument.
