Summary:                    [patch] downsampling slinear16 to slinear (or ulaw
or alaw or g729) results in truncation
Description: 
When I translate from AST_FORMAT_SLINEAR16 to AST_FORMAT_SLINEAR the output
frame is truncated, specifically, instead of 160 samples I get 137 samples.
The result is the same for ulaw and alaw. For g729, the output is truncated
to 80 samples.

---------------------------------------------------------------------- 
Also, just as a note, in my case, I have codec_resample loaded and it's
using that as the translation path.  Results may be different if that
module is not loaded, and translation goes through codec_g722.
