[issue13806] Audioop decompression frames size check fix

[Oleg Plakhotnyuk]

New submission from Oleg Plakhotnyuk <olegus8 at gmail.com>:

According to documentation (http://docs.python.org/library/audioop.html), adpcm2lin, alaw2lin and ulaw2lin are using 'width' argument to represent output frames width. However, in audioop.c module there are checks that are raising exceptions if input frames length is not multiple of 'width'. I have replaced checking of 'len' to match 'size' with checking of 'len*size' to match 'size' in order to retain only basic length validity checks.
