Tweaks for www.gnu.org html versions of manuals

* doc/lispintro/emacs-lisp-intro.texi: Add some stuff specific to www.gnu.org.

(socket_connection) [!HAVE_KRB5_ERROR_TEXT && HAVE_KRB5_ERROR_E_TEXT]:
Use ERROR_MAX, not ERRMAX.
* leim/quail/latin-ltx.el: Resolve conflicts.
(latin-ltx--mark-map, latin-ltx--mark-re): New constants.
(latin-ltx--define-rules): Check for conflicts.  Eval `re's.
(rules): Use tighter regexps to avoid conflicts.
Consolidate the various rules for combining marks.
* admin/admin.el (manual-pdf, manual-dvi): Pass -I to texi2pdf, texi2dvi.
* thingatpt.el (end-of-sexp): Fix bug#13952.
* thingatpt.el (end-of-sexp): Use syntax-after.
* lisp/emacs-lisp/smie.el (smie-auto-fill): Don't inf-loop if there's no
token before point.
* progmodes/scheme.el: Add indentation and font-locking for λ.
* iswitchb.el (iswitchb-read-buffer): Fix typo.
