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
- * $Log$
- * Revision 1.2  2006/02/22  16:56:01  arthchan2003
- * Merged from SPHINX3_5_2_RCI_IRII_BRANCH: Added ms_mgau.[ch] into the trunk. It is a wrapper of ms_gauden and ms_senone
- * 
- * Revision 1.1.2.4  2005/09/25 18:55:19  arthchan2003
- * Added a flag to turn on and off precomputation.
- *
- * Revision 1.1.2.3  2005/08/03 18:53:44  dhdfu
- * Add memory deallocation functions.  Also move all the initialization
- * of ms_mgau_model_t into ms_mgau_init (duh!), which entails removing it
- * from decode_anytopo and friends.
- *
- * Revision 1.1.2.2  2005/08/02 21:05:38  arthchan2003
- * 1, Added dist and mgau_active as intermediate variable for computation. 2, Added ms_cont_mgau_frame_eval, which is a multi stream version of GMM computation mainly s3.0 family of tools. 3, Fixed dox-doc.
- *
- * Revision 1.1.2.1  2005/07/20 19:37:09  arthchan2003
- * Added a multi-stream cont_mgau (ms_mgau) which is a wrapper of both gauden and senone.  Add ms_mgau_init and model_set_mllr.  This allow eliminating 600 lines of code in decode_anytopo/align/allphone.
