-- defsymbol -> DEFSYMBOL.
-- add an error type to all errors.
-- eliminate the error functions in eval.c that let you just
use Qerror as the type.
-- redo the error API to be more consistent, sensibly named,
and easier to use.
-- redo the error hierarchy somewhat. create new errors:
structure-formation-error, gui-error, invalid-constant,
stack-overflow, out-of-memory, process-error, network-error,
sound-error, printing-unreadable-object, base64-conversion-
error; coding-system-error renamed to text-conversion error;
some others.
-- fix Mule problems in error strings in emodules.c, tooltalk.c.
-- fix error handling in mswin open-network-stream.
-- Mule-ize all sound files and clean up the headers.
-- nativesound.h -> sound.h and used for all sound files.
-- move some shared stuff into glyphs-shared.c: first attempt
at eliminating some of the massive GTK code duplication.
xemacs.mak: add glyphs-shared.c.
xemacs-faq.texi: document how to debug X errors
subr.el: fix doc string to reflect reality
