mpeg12: Ignore slice threading if hwaccel is active
Conflicts:
libavcodec/mpeg12dec.c
Merged-by: Michael Niedermayer <michaelni@gmx.at>
Slice threading does not work with hardware acceleration, as decoding
is per-picture. This fixes Bugzilla #542.

VDPAU expects the bitstream value (0, 2 or 3).
libavcodec uses an enum (0, 1 or 2).

When building for iOS in thumb mode, gas-preprocessor.pl doesn't
mark unused labels as thumb functions (as it does for other
local labels, where it can figure out that they are functions
due to being referenced in branch instructions). This leads to
linker warnings for some of those local labels, such as:
ld: warning: ARM function not 4-byte aligned: __a_evaluation from
libavcodec/libavcodec.a(simple_idct_arm.o)
Therefore, comment them out since they don't have any function.
They do still have a value in documenting key points in the
assembly source though.

4xm: Reject not a multiple of 16 dimension
The newly added checks are redundant and thus replaced by asserts

A lock manager is not the only possibility to avoid open/close locking
issues but its easier and more robust than maintaining a lot of lock/unlock
calls.

This is similar to int32_to_float_fmul_scalar, but
loads a new scalar multiplier every 8 input samples.
This enables the use of much larger input arrays, which
is important for pipelining on some CPUs (such as
ARMv6).
