0747754622 mpeg4audio: validate sample_rate
A negative sample rate doesn't make sense and triggers assertions in
av_rescale_rnd.

Also check for errors from avpriv_mpeg4audio_get_config in
ff_mp4_read_dec_config_descr.

fd095539d1 latmdec: fix audio specific config parsing
Pass the correct size in bits to mpeg4audio_get_config and add a flag
to disable parsing of the sync extension when the size is not known.

Latm with AudioMuxVersion 0 does not specify the size of the audio
specific config. Data after the audio specific config can be
misinterpreted as sync extension resulting in random and wrong configs.
