The specification does not prevent an encoder to write the amplitude 0
as 0 amplitude_bits.
Our get_bits() implementation might not support a zero sized read
properly, thus the additional branch.
The value is used to calculate output LSP curve and a division by zero
and out of array accesses would occur.
CVE-2013-0894

"channels" is an int in all the other places in the libraries, and the
av_frame_*_channels() accessors return and set an int, so this should not
implicate ABI breaks.
Previously avctx->hwaccel would have been set to a dummy value,
now an explicit check is necessary instead.

As the name indicates we can't just assume what the
"opaque" field contains.
This fixes a crash in third-party applications see e.g.:
http://bugzilla.mplayerhq.hu/show_bug.cgi?id=2126
This fixes also FFmpeg trac #2293, which is a different
third-party application.

If you want it back (yeah i want it back too)
then you just need to volunteer to maintain the code in configure
thats related to hwaccel autodetection.
