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.

It only affects the old and deprecated avcodec_decode_(video2|audio4)
API which is no longer used here.

Previously if only -y was used then nothing happened, if only -x then zero
window height was set which is undefined in SDL and caused a black window.
From now on if only one dimension is set we calculate the other based on
size/aspect of the shown content.

SDL from version 2.0.8 has support for full range YUV and specifying
BT601/BT709 color space for YUV->RGB conversion.

Current ffplay code assumes that the read thread is in its main loop before any
key events are captured, but apparently on IOS even keypresses without a window
are forwared.
Fixes ticket #7252.

SDL_QueryTexture and SDL_DestroyTexture require that the input texture
pointer be non-null. Debug builds of SDL will correctly check for this
and break program execution. This patch fixes this by checking the
status of the texture pointer.

avdevice_register_all() is still required to register devices into
lavf (this is required due to lavd being somewhat of a hack).

Typically only a small subset of the SDL texture formats are supported directly
by the SDL renderer drivers, the rest is software emulated. It's better if
libswscale does the format conversion to a hardware-accelerated texture format
instead of SDL.
This should fix video render slowdowns with some texture formats after
3bd2228d05.
