audio: unify input and output mixeng buffer management

Browse Source 
Usage notes: hw->samples became hw->{mix,conv}_buf->size, except before
initialization (audio_pcm_hw_alloc_resources_*), hw->samples gives the
initial size of the STSampleBuffer.  The next commit tries to fix this
inconsistency.
