The older av_fifo_realloc2 implemented an auto grow that
should be ported as such in the new API.
This patch introduces a limitation in the fifo buffer size.
The default is set to 128MB and may be overriden by a new user option.
The amount of memory allocated depends on multiple factors,
The first patch is left unchanged since v4.
The second has been totally reworked after some investigations advised by
Andreas.

Disable ff_add_pixels_clamped_arm, which was found to fail the test. As this

that anyone is still using this, so I haven't put in the effort to debug it.

Upstream gained a new tone-mapping API, which we never switched to. We
don't need a version bump for this because it was included as part of
the v4.192 release we currently already depend on.
Some of the old options can be moderately approximated with the new API,

While the capabilities API is in principle meant to be used with an
