Portability fixes (now it compiles & runs fine on Solaris).

lib-src/emacsclient.c: Removed tty proxy kludge.  Emacs should just
use the same terminal as emacsclient.
(ec_get_tty, ec_set_tty, master, pty_name, old_tty, tty, old_tty_valid)
(tty_erase_char, quit_char, flow_control, meta_key, _sobuf, init_tty)
(window_change, reset_tty, init_pty, copy_from_to)
(pty_conversation): Removed.
(window_change_signal): Just forward the signal to Emacs, don't do
anything else.
(init_signals): Don't set handlers for SIGHUP & SIGINT.
(strprefix): New function.
(main): Don't touch the terminal, simply tell its name to Emacs.

lisp/server.el (server-frames): Changed name and semantics to server-ttys.
(server-tty-live-p): New function.
(server-sentinel): Delete the whole tty, not just the frame.
(server-handle-delete-frame): Removed.
(server-handle-delete-tty): New function. Close the client connection if
the tty is deleted.
(server-start): Clean up server-ttys, not server-frames.  Set up
delete-tty-after-functions.
(server-process-filter): Set up server-ttys, not server-frames.
Updated protocol for sending our pid to emacsclient.
(server-buffer-done): Don't delete the client process directly, delete
the tty instead, and rely on the delete-tty hook to close the
connection.  Otherwise the terminal could be left in a bad state.

src/cm.c (cmputc): Don't abort on write errors.

src/indent.c: #include <stdio.h>, for termchar.h.
src/window.c: Ditto.
src/xfaces.c: Ditto.

src/sysdep.c (init_sigio, reset_sigio, request_sigio)[!SIGIO]
(unrequest_sigio)[!SIGIO]: If SIGIO is not supported, don't do
anything. (For Solaris.)
(init_sys_modes): Moved tty_set_terminal_modes call back to here,
disable window system check.
(reset_sys_modes): Reset the terminal even if X is running.

src/term.c (Vdelete_tty_after_functions): New variable.
(syms_of_term): Initialize it.
(Fdelete_tty): Updated docs.
(delete_tty): Run delete-tty-after-functions.
(term_init): Removed tty_set_terminal_modes call.
