Clipping the picture place computes incorrect values, which cannot be
used for correct rendering. Instead the place should never be clipped,
and the picture should be cropped if one or both coordinates are
negative, or one or both dimensions exceeds the display dimensions.

Fortunately, only one video output used the broken mode.

This cannot possibly result in correct picture scale and position, but
then again, this was already the case before this change.

(if NEON is disabled in the C compiler settings)

This only assumes NEON is available on AArch64 if it is actually
enabled in the compiler settings (or rather, not explicitly disabled).
Otherwise, perform regular run-time detection.

This carried no data, was rarely used and waste 12 bytes per format.

And fix big endian support.

This probably never worked.

RGB shifts carry zero entropy as they can trivially be recomputed from
the RGB masks. And then, they were only two users.

This saves 12 bytes per format.

The RGB converter only cares about right shifts to extract component
values. No need to copy the whole enourmous video format.

This avoids overflowing into the sign bit when shifting to left.
Also stop caring about alleged GCC 3.4 bugs.

Fixes #21349

This was broken since 10887807.

This is done when we need to guess the best pick for all color space values.

In many cases we don't know the value so it's better to use UNDEF.

A boolean also prevents from overwriting a value only when it's undefined.

The es_out display now separates the color space and the color range. One may
be known without the other.

There are cases were we don't know the range. It's better not to write 0 as if
we knew.

Seems to fix issues with CBC modes

Replaces the timestamp FIFO.

Otherwise we will always have a format update on the first output.

update the ffmpeg hash to use the latest API changes of dav1d

Breakpad.xib is in the old Xcode3 format, supporting OS versions
down to 10.5. This old target is not supported anymore by new
toolchains, therefore upgrade the format with Xcode 10, and set
10.7 as minimum version.
