Fixes#10759.
It can happen in H.264, MPEG2, VC1 that the current frame resource
memory is already in ref_resource. For example, for a interlaced frame,
the same curr memory is passed twice. For the second time it could possibly
reference itself. When this happens the curr is already given an index and
in ref_resources. When the reference frame index is required, we should check
the existance in the ref_resources first before assigning a new index for it.

This file has been exported since our minimum required version (0.7.0),
but it wasn't documented. Instead it was transitively included by
<jxl/decode.h> (but not jxl/encode.h), which ffmpeg relied on.
libjxl broke its API in libjxl/libjxl@66b9592393 by removing
the transitive include of version.h, and they do not plan on adding
it back. Instead they are choosing to leave the API backwards-
incompatible with downstream callers written for some fairly recent
versions of their API.
As a result, we include <jxl/version.h> to continue to build against
more recent versions of libjxl. The version macros removed are also
present in that file, so we no longer need to redefine them.

Avoids casts all over the place; in this case, it also
replaces the unsafe cast uint8_t**->const uint8_t **
by the safe cast uint8_t**->const uint8_t * const*.

Sort options by name, review formatting, apply consistency fixes and
fill the gaps (e.g. missing value for constants or flags), and review
and extend content.

VVC specifies << as arithmetic left shift, i.e. x << y is equivalent to
x * pow2(y). C's << on the other hand has UB if x is negative. This
patch removes all UB resulting from this, mostly by replacing x << y
with x * (1 << y), but there are also a couple places where the OOP was
changed instead.
