Message:

• Bring speex codec up to date with their SVN trunk
• Speex codec should work in FIXED_POINT mode when PJ_HAS_FLOATING_POINT is set to zero.
• ulaw2linear will return zero if zero is given (this would make the VAD works better, and it also fixed click noise when call is established/hangup).
