Log Message:
-----------
Speex changed its interface to VAD probabilities.  In early 1.1 dev versions
VAD probabilities were floats.  In 1.2beta1, the probabilities are 32 bit ints.
Iaxclient still passed pointers to floats as arguments, and this forced speex
to use its built in defaults.  In effect our VAD probability tweaks did nothing.
This change attempts to fix this by converting VAD probability arguments to 
32 bit integers ranging from 0 to 100.
