the last avpacket (in case of frame threading, it won't be the

generator parameters when a packet is given to it for decoding,
but if called with an empty packet, it generates more noise

e2ff436ef6 lavc: Relax API strictness in avcodec_decode_audio3 with a custom get_buffer() 
Do not fail audio decoding with avcodec_decode_audio3 if user has set a
custom get_buffer. Strictly speaking, this was never allowed by the API,
but it seems that some software packages did so anyways. In order to
unbreak applications (cf. http://bugs.debian.org/655890), this change
clarifies the API and overrides the custom get_buffer() with the defaults.

This change is inspired by a similar
commit (c3846e3eba) in FFmpeg.

1b6da627d4 avcodec: Remove a misplaced and useless attribute_deprecated 
If attribute_deprecated is used in an enum declaration, it
should follow the 'enum' keyword, otherwise it's ignored
silently. This is the only case of attribute_deprecated for
enum declarations currently.

Currently, this attribute_deprecated doesn't have any effect.
If moved to the right place, it emits a warning every single
time avcodec.h is included, like this:

avcodec.h:2827: warning: ‘AVLPCType’ is deprecated (declared at avcodec.h:543)

There is already a working attribute_deprecated for the
corresponding field in AVCodecContext, so therefore this
one shouldn't be needed.
