(server-start): Don't remove the file of the previous process, but
instead clear out the place for the new file.
(server-start): Set the :auth-key property.
(server-process-filter): Use the :auth-key property.
(server-process-filter): When authentication fails, send error message to
client. Wrap `process-send-region' in `ignore-errors' instead of
`condition-case', and remove misleading comment.
(server-use-tcp, server-host, server-auth-dir): New options.
(server-auth-key): New variable.
(server-ensure-safe-dir): Create nonexistent parent dirs. Ignore Unix-style
file modes on Windows.
(server-start): Crete a TCP or Unix socket according to the value of
`server-use-tcp'. For TCP sockets, create the id/auth file in `server-auth-dir'
directory.
(server-process-filter): Delete process if authentication fails (which never
happens for Unix sockets).
(server-process-filter): Add support for `-display' and `-eval' args.
(server-visit-files): Use save-current-buffer, push, and dolist.
Add server-kill-buffer to kill-buffer-hook.
(kill-buffer-hook): Don't modify globally.

Normalize file name after unquoting and decoding.
(server-buffer-done): Just close the connection.
(server-switch-buffer): Handle the case where all windows are
dedicated or minibuffers.
(server-switch-buffer): Only select a different window if
next-buffer is non-nil. Don't switch in a dedicated window.
If next-buffer is already displayed, reuse that window.
(server-start): Don't bother canceling the sentinel.
(server-process-filter): Use replace-regexp-in-string and
handle the new &n quoting. Use push. Use server-log's new arg.
Don't output the C-x # message if `nowait'.
