Fixes a decoding regression introduced by e9a2a877, and as a side effect also
fixes bogus values set to certain audio frames that had some samples discarded,
where the offsets added to pts, pkt_dts and pkt_duration were not reflected in
best_effort_timestamp.

One of the inputs to the fate test has an rgba pixel format which needs
to be converted to rgb32 (argb on big-endian) for the hqx filter. Because auto
scaling in the fate test is disabled, this needs a separate scale
filter.

Fixes fate-qtrle-32bit on big-endian.

The macro does a simple byte swap on uint8 array without any casts, so
it's valid on big-endian arches.

The mentioned test was failing because the byteswap function
shuffle_bytes_3210_c() is used in the pixel format conversion
(argb->bgra).

Up until now, the SpeedHQ encoder called a wrong function for init:
void ff_init_uni_ac_vlc(const uint8_t huff_size_ac[256],
                        uint8_t *uni_ac_vlc_len);
Yet the first argument actually used is of type RLTable; the size of
said struct is less than 256 if the size of a pointer is four, leading
to an access beyond the end of the RLTable.

This commit fixes this by calling the actually intended function:
init_uni_ac_vlc() from mpeg12enc.c. It was intended to use this
function [1], yet doing so was forgotten when the patch was actually
applied.

The earlier code would not complain if the remaining size was one byte
short of the desired size; and the way it performed the check could run
into signed integer overflow.
