SDL supports only these three matrices. Actually, it only supports these
three combinations: BT.601+JPEG, BT.601+MPEG, BT.709+MPEG, but we have
no way to restrict the specific *combination* of YUV range and YUV
colorspace with the current filter design.

Instead of an incorrect conversion result, trying to play a YCgCo file
with ffplay will simply error out with a "No conversion possible" error.
This commit lets ffplay properly propagate YUV metadata into the filter
graph, avoiding such issues as e.g. accidentally passing YCgCo into a
filter that can't support it. Also fixes an error related to this
missing metadata from buffersrc (since commit 2d555dc82d)

This option flag only carries nontrivial information for options that
call a function, in all other cases its presence can be inferred from
the option type (bool options do not have arguments, all other types do)
and is thus nothing but useless clutter.
Change the option parsing code to infer its value when it can, and drop
the flag from options where it's not needed.
Not sure if the function naming frame_queue_destory is intended because
"destory" is not really a word. Changing it to "destroy" makes more sense.

For example, if the jpeg contains exif information
and the rotation direction is included in the exif,
the displaymatrix will be set on the side_data of the frame when decoding.
However, when ffplay is used to play the image,
only the side data in the stream will be determined.
It does not check whether the frame also contains rotation information,
causing it to play in the wrong direction

GL and Metal cache the state at time of texture creation. GLES2 and
Direct3D 11 use the state at time of the render copy call.
So the only way we can get the correct behavior consistently is by
making sure the state is set for both the upload *and* the draw call.
This probably isn't our bug to fix (upstream should make itself behave
consistently and also document its functions), but as it stands,
`ffplay` is misrendering BT.709 as BT.601 on my stock Linux system, and
that leaves a bad taste in my mouth.

It tries to process any unhandled options as AVOptions. Handle this
directly in cmdutils.c, without resorting to a confusing fake option
definition (which is currently visible to the users in -help output).
This avoids unnecessary rebuilds of most source files if only the
list of enabled components has changed, but not the other properties
of the build, set in config.h.

If the window is resized it was possible that xpos pointed outside the
visualization texture. By rearranging the overflow check we make sure this (and
a crash) does not happen.
We also don't have to use xleft for start position, as that is 0 anyways, and
if we ever want to take into account xleft then the texture should be
positioned accordingly when rendering.

The obstacle to do so was in filter_codec_opts: It uses searches
the AVCodec for options via the AV_OPT_SEARCH_FAKE_OBJ method, which
requires using a void * that points to a pointer to a const AVClass.
When using const AVCodec *, one can not simply use a pointer that points
to the AVCodec's pointer to its AVClass, as said pointer is const, too.
This is fixed by using a temporary pointer to the AVClass.
