gst_buffer_extract returns the number of bytes extracted, here 2 max.
Set size to the buffer size as was done in 0.10 to avoid first_access
error when it bypass 2.

and use fixed caps on the srcpad. To correctly support
upstream renegotiation a52dec would need to check if the
caps of the downstream allocated buffer are the requested
caps or if the size is different.
Fixes bug #665989.
liba52 in a52dec-0.7.4 does not have any MMX, MMXEXT or 3DNOW based
IMDCT transform acceleration. It does however have a software based
acceleration using the djbfft library (D.J. Bernstein's library for
fourier transforms - Extremely fast library for floating-point
convolution). So allow liba52 to use it through the MM_ACCEL_DJBFFT
flag.
The liba52 copy in MPlayer sources does have SSE, 3dnowext, 3dnow
and AltiVec implementations, but those are checked for first, and
djbfft is chosen only if none of those is available - good in the
case of some distributions including a port of the MPlayer changes
in their system a52dec library.
The down and upmix code in liba52 doesn't seem to be disturbed by
this additional MM_ACCEL flag and will still use MMX, SSE or 3DNOW
versions if passed from oil_cpu_get_flags (SSE currently is not).
Fixes bug #592787.
Perform some cleanups based on the dtsdec code such as using the boilerplate
macro and static pad template functions.
Add some documentation. Don't register a change in flags until we synch on
another frame successfully.

Add missing elements to docs. Restore alphabetical order in section
file. Document mad (it was included in docs already).
Fix doc-markup: use convinience syntax for examples
(produces valid docbook), add several refsec2 when we have several
titles. Fix some types.

Patch from from Michal Benes <michal.benes@itonis.tv>:
Add two things to a52dec: configure the exact output format for ac3
decoding through properties, if desired.
By default, configure an output format preferred by downstream. Now
that audioconvert lists caps by preference, this means that a52dec
can do downmixing (iff required) rather than audioconvert, so it can
use the ac3 downmix levels from the bitstream.

Instead of forwarding the event in the wrong format, unref it and set
a boolean that we still need to send it in the streaming thread.
