Only use PAL8 if palette is present, else use GRAY8 for pixfmt.

Instead of simulating a grayscale palette, use real grayscale pixels, if no
palette is actually defined.

1) each of the loops run within a single CTB, so the relevant reference
list is constant
2) when that CTB is, or lies on the same slice as, the current one, we
can use a simple access instead of a relatively expensive call to
ff_hevc_get_ref_list()

It makes no sense and cannot happen in any place from which this
function is called.

Use named constants instead of magic numbers, avoid using variables with
inverse meaning from what their name implies.

The if() around those loops ensures this condition is always false.

ff_hevc_deblocking_boundary_strengths() is never called if the
deblocking filter is disabled for the slice.

The Xvid IDCT is not MMX-specific.

This fixes cases where the scantable permuation would get overwritten by
the general idctdsp initialization.

Standalone GNU assembly is not used on x86.

sws_getCachedContext is not a full replacement for the function.

It allows attaching other external, opaque data to the frame and passing it
through the reordering process, for cases when the caller wants other data
than just the plain packet pts.  There is no way to cleanly achieve this
without the field.

Column and row frame packing arrangements were inverted.

An encoding ("encd") box is required to tell QT that the string is UTF8

The input data must remain constant, make a copy instead. This is in
theory a performance hit, but since I failed to find any samples
using this feature, this should not matter in practice.

Also, check the size of the header, avoiding invalid reads on truncated
data.
