From the ARMv7 NEON version. 16 times faster as the C version, overall
more than 12% faster vorbis decoding on Apple's A7.

30%/25% (fixed/float) faster mp3 decoding on Apple's A7. The floating
point decoder is approximately 7% faster.

Approximately as fast as the ARM NEON version on Apple's A7.

The picture slot can be recycled by select_input_picture and
only current_picture is populated with the valid pts.

Also set the RGBA pixel format correctly as the native endian format,
which is what it returns.

This fixes the tests on big endian.

avctx->coded_{height,width} will always equal h->{height,width} since
init_dimensions() does that explicitly, Size changes are detected by
changes in mb_{height,width} earlier and propagated through the
needs_reinit variable.

This array is written using AV_WN32A, assuming alignment.

This hopefully fixes the failing vp7 fate test on sparc.

No initialization is needed in dca_decode_frame, because the next
thing it does is calling dca_parse_frame_header, which takes care of
the needed initialization.

Also add additional known values and log as missing features.

The spec does not specify that 0 is an error condition, and there
are samples which use 0 when the whole image is in one strip.

The most interesting parts are initialization in ff_MPV_common_init() and
uninitialization in ff_MPV_common_end().

ff_mpeg_unref_picture and ff_thread_release_buffer have additional NULL
checks for Picture.f, because these functions can be called on
uninitialized or partially initialized Pictures.

NULL pointer checks are added to ff_thread_release_buffer() stub function.
