6ca23db9cc ac3enc: modify mantissa bit counting to keep bap counts for all values of bap 
instead of just 0 to 4.

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

1323828a0f ac3enc: split mantissa bit counting into a separate function. 
No speed difference. This is to allow for more flexible bit counting.

7743865ffc ac3enc: store per-block/channel bap pointers by reference block in a 2D array 
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.

7f7726c7a2 ac3enc: use LOCAL_ALIGNED macro 
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.

26513856d6 cmdutils: remove OPT_FUNC2 
Make ff* tools only accept opt_* functions taking two arguments.

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

79aeade6f6 ARM: disable ff_vector_fmul_vfp on VFPv3 systems 
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.
