Using AVOnce as a stack variable makes no sense as the state is lost
when the function exits.

This fixes repeated calls to av(filter/device)_register_all

Takes a frame associated with a hardware context as input and maps it
to something else (another hardware frame or normal memory) for other
processing.  If the frame to map was originally in the target format
(but mapped to something else), the original frame is output.

Also supports mapping backwards, where only the output has a hardware
context.  The link immediately before will be supplied with mapped
hardware frames which it can write directly into, and this filter
then unmaps them back to the actual hardware frames.

This is a similar filter to f_metadata, only it works on side data. Since
adding side data from a user provided arbitrary binary string is unsafe,
because current code assumes that a side data of a certain kind has the proper
size, this filter only implements selection and deletion. Also, no value
matching support is implemented yet, because there is no uniform way to specify
a side data textually.

Fixes ticket #4441.

The intent here is similar to colormatrix, but it's LGPLv2.1-or-later
(instead of GPLv2.0) and supports gamma/chromaticity correction.
