echo-cancel: Add function pa_echo_canceller_blocksize_power2()

Browse source 
computes EC block size in frames (rounded down to nearest power-of-2) based
on sample rate and milliseconds

move code from speex AEC implementation to module-echo-cancel such that
functionality can be reused by other AEC implementations
