#1053: Crash on avcodec_default_release_buffer

----------------------------------+-------------------------------------
When allocating an internal buffer for an audio frame, audio_get_buffer in
libavcodec/utils.c does not increment buffer_count. This results in
incorrect behavior of avcodec_default_release_buffer (it attempts to
FFSWAP InternalBuffer when buf is NULL) for this frame and consequently a
crash with SIGSEGV.
Please, find a simple test case attached that reproduce the problem.
Compiled with the following command line:
{{{
gcc -o av_internal_buf_crash -lavcodec -lavutil av_internal_buf_crash.c
}}}
