Purge SXEmacs of tooltalk and CDE cruft -- docs, autoconf

Tooltalk was some old Sun/Sparcworks thingamajiggy.  Nobody uses it
anymore and it has been superseded by D-Bus anyway.  Even though SXEmacs
doesn't yet have full (any?) D-Bus support we're nuking this silly
tooltalk madness now.

This changeset removes the tooltalk cruft from our build chain autotool
stuff and from the docs.

	* configure.ac: Remove all the tooltalk and CDE cruft.

	* m4/sxe-summary.m4 (SXE_SUMMARY): Ditto.

	* etc/PACKAGES: Ditto.

	* info/sxemacs-faq.texi (Q4.4.2): Removed.
	  Plus nuke other mentions of tooltalk.

	* info/sxemacs/packages.texi (Available Packages): Remove
	  tooltalk. Yes I know that the tooltalk XEmacs package is still
	  available, but there's not much point in saying so in the SXEmacs
	  manual if SXEmacs doesn't support tooltalk at all.

	* info/lispref/objects.texi: Remove all the tooltalk cruft.

	* info/lispref/lispref.texi: Ditto.

	* info/lispref/hooks.texi (Standard Hooks): Ditto.

	* info/lispref/errors.texi (Standard Errors): Ditto.

	* info/internals/internals.texi: Ditto.

	* info/lispref/ldap.texi (LDAP Support): Set prev node to
	  X-Windows.  Skips tooltalk.

	* info/lispref/x-windows.texi (X-Windows): Set next node to LDAP
	  Support.  Skips tooltalk.
