Another GPM change...

This adds support for GPM on multiple VCs using 'gnuclient', adds a lisp-level (gpm-enabled-p) function, and reworks the gpm.el code. It also now hooks delete-device-hook instead of kill-emacs-hook, so that the GPM stuff gets shut down correctly if you connect to a XEmacs running in X, then kill the tty connection. It is also safe now to call (progn (gpm-enable nil t) (gpm-enable nil nil) (gpm-enable nil nil)) Last round of patches it would explode because of insufficient checking of the return value of Fget_process. The GPM processes are now named uniquely for what TTY they are attached to. Well, lunch is over, time to get back to real work. :( No patch because they are all longer than the files now. If anybody on linux could try this out, I would appreciate it. With this, I'm pretty close to happy using it instead of X on my linux w/frame-buffer support compiled in. The screen is sure a lot wider :) -Bill P.
