Issue #1538 - remove speech recognition engine

This removes speech recognition, pocketsphinx, training models
and the speech automated test interface.
This also re-establishes proper use of MOZ_WEBSPEECH to work
for the speech API (synthesis part only) that was a broken mess
before, with some synth parts being always built, some parts
being built only with it enabled and recognition parts being
dependent on it. I'm pretty sure it'd be totally busted if you'd
ever have tried building without MOZ_WEBPEECH before.

Tested that synthesis still works as-intended.

This resolves #1538

- * HISTORY
- * $Log: tmat.c,v $
- * Revision 1.1.1.1  2006/05/23 18:45:01  dhuggins
- * re-importation
- *
- * Revision 1.4  2005/11/14 16:14:34  dhuggins
- * Use LOG() instead of logs3() for loading tmats, makes startup
- * ***much*** faster.
- *
- * Revision 1.3  2005/10/10 14:50:35  dhuggins
- * Deal properly with empty transition matrices.
- *
- * Revision 1.2  2005/09/30 15:01:23  dhuggins
- * More robust tmat reading - read the tmat in accordance with the fixed s2 topology
- *
- * Revision 1.1  2005/09/29 21:51:19  dhuggins
- * Add support for Sphinx3 tmat files.  Amazingly enough, it Just Works
- * (but it isn't terribly robust)
- *
- * Revision 1.6  2005/07/05 13:12:39  dhdfu
- * Add new arguments to logs3_init() in some tests, main_ep
- *
- * Revision 1.5  2005/06/21 19:23:35  arthchan2003
- * 1, Fixed doxygen documentation. 2, Added $ keyword.
- *
- * Revision 1.5  2005/05/03 04:09:09  archan
- * Implemented the heart of word copy search. For every ci-phone, every word end, a tree will be allocated to preserve its pathscore.  This is different from 3.5 or below, only the best score for a particular ci-phone, regardless of the word-ends will be preserved at every frame.  The graph propagation will not collect unused word tree at this point. srch_WST_propagate_wd_lv2 is also as the most stupid in the century.  But well, after all, everything needs a start.  I will then really get the results from the search and see how it looks.
- *
- * Revision 1.4  2005/04/21 23:50:26  archan
- * Some more refactoring on the how reporting of structures inside kbcore_t is done, it is now 50% nice. Also added class-based LM test case into test-decode.sh.in.  At this moment, everything in search mode 5 is already done.  It is time to test the idea whether the search can really be used.
- *
- * Revision 1.3  2005/03/30 01:22:47  archan
- * Fixed mistakes in last updates. Add
- *
- * 
- * 20.Apr.2001  RAH (rhoughton@mediasite.com, ricky.houghton@cs.cmu.edu)
- *              Added tmat_free to free allocated memory 
- *
- * 29-Feb-2000	M K Ravishankar (rkm@cs.cmu.edu) at Carnegie Mellon University.
- * 		Added tmat_chk_1skip(), and made tmat_chk_uppertri() public.
- * 
- * 10-Dec-1999	M K Ravishankar (rkm@cs.cmu.edu) at Carnegie Mellon University.
- * 		Made tmat_dump() public.
- * 
- * 11-Mar-97	M K Ravishankar (rkm@cs.cmu.edu) at Carnegie Mellon University.
- * 		Started based on original S3 implementation.
