Patches for Thai support

Patches for Thai support

The handling of composite sequences for Thai is overly simplistic as
regards handling of diacritics.  To give just one example, you can't
have a tone mark over a maitaikhu. There's a Thai standard called WTT
2.0 that gives the precise rules.  WTT 2.0 also has some extensions to
the Kesmanee keyboard layout that are fairly universal on keyboard used
Thailand today. There's an English language description of all of this
at:

http://www.nectec.or.th/it-standards/keyboard_layout/thai-key.htm

Attached is a patch against the current CVS Emacs that fixes the Thai
support to match WTT 2.0.  It's only lightly tested.

There are some more fundamental issues with the support for Thai (and
other South and South-East Asian languages that rely heavily on
combining characters).  More about these later.

Thank you for the contribution.  I'll take a look at it soon
(currently I'm too overloaded).  But, as the patch is not
tiny, we need your assignment paper to adopt it.  Please ask
RMS <rms@gnu.org> about it.
