This does all the actual bit counting as a final step.

No speed difference. This is to allow for more flexible bit counting.

rather than in the AC3Block struct.

This will make it easier to access the bap values without having to chase
the reference block pointers each time.

This silences numerous compiler warnings from skip_bits(),
where the cache variable is not used.

This uses one register less.  Also add missing "cc" clobber.

Aligned local variables must use the LOCAL_ALIGNED macro to ensure
correct alignment on all systems.  The unusual size argument to
memset is required since the implementation of LOCAL_ALIGNED may
use a pointer to an array.

The distinction between functions with one and two arguments is quite
pointless. Simplify parse_options() code.

Create a stereo_mode metadata tag to specify the stereo 3d video layout
using the StereoMode tag in a matroska/webm video track.

This adds basic stream format support and allows for arbitrary bit rates
rather than just those supported in AC-3.

use only selected options for the different AC-3 encoder types.

This function uses old-style vector operations deprecated in VFPv3.
Some implementations, e.g. Cortex-A9, support them only through
slow software emulation.  Cortex-A8 does have this functionality
in hardware, but as it also has NEON, this function is not used
there regardless.

nasm versions prior to 2.09 have trouble assembling some of our AVX code.
Protect these sections by preprocessor macros to allow compilation to pass.

av_freep(swsContext) will leak all memory potentially
allocated within the swsContext.

That means it won't be allocated when not needed. Alongside
this, it fixes valgrind/fate-detected memory leaks.
