19c5fa9eea golomb: Simplify get_ur_golomb_jpegls 
The loop always consumes the bit read and the new bitstream reader
can read 0 bits just fine.

1fe858136b utvideodec: Prevent possible signed overflow 
Doing slice_end - slice_start is unsafe and can lead to undefined behavior
until slice_end has been properly sanitized.

10f4511f14 libavutil: Make LOCAL_ALIGNED(xx be equal to LOCAL_ALIGNED_xx( 
Previously, the former form always produced a manually aligned,
padded buffer, while the latter can use DECLARE_ALIGNED, if that
amount of stack alignment is supported.

libavutil/internal.h needs to include mem.h, since it uses
the DECLARE_ALIGNED macro.

e788ca05a7 hevcdec: Use LOCAL_ALIGNED_* for declaring local variables with alignment 
Not all compilers can do alignment larger than the normal stack alignment
for variables on the stack. In these cases, the LOCAL_ALIGNED_* macros
produce the workaround alignment wrapper consisting of a padded array
and a pointer variable.

This fixes the hevc fate tests on RVCT/ARMCC after adding IDCT assembly
that actually assumes/relies on this alignment.
