In order to work correctly with the i965 driver, this also fixes the
direction of forward/backward references - forward references are
intended to be those from the past to the current frame, not from the
current frame to the future.

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.

The data types within the MvField struct themselves imply 4 byte alignment.

libavformat/takdec.c:144:20: warning: format '%X' expects argument of type 'unsigned int', but argument 4 has type 'uint32_t'

num_core_channels is always equal to s->audio_header.prim_channels,
neither one of those variables ever get changed.

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.

The main hevcdsp.c file calls this init function if HAVE_ARM is set,
regardless of whether neon support is available or not.

This fixes builds where neon isn't supported by the build tools at all.

Also use that to fix a warning in av_hwdevice_get_type_name().

These compilers pass the inline assembly check, but fail to compile
our inline assembly in various ways.

Fixes invalid reads with corrupted files.

Replicates lavf/librtmp.c behavior in L145-152 and rtmpdump's
behavior with "--swfVfy <url>" passing the url to swfUrl.

Fixes bug 943.

Otherwise inline assembly may get enabled when disabled on the command line.

Avoid confusion.

These values are defined to be 32bit in the specification,
so it makes more sense to store them as fixed width.
