The workaround need to be enabled per pci id which can not
be detected inside ffmpeg. So this adds a flag that enabled
the alternate behavior.

So it is more clear the context of the sentence.

This is required, or avcodec_open() will abort because of invalid
sample format.

It's required to be non-zero since
cc58300e

There's no point in keeping them separate.

Those are reserved for the libs.

They were replaced by (de)muxer private options.

Deprecate AVFormatContext.loop_output.

Deprecate AVFormatContext.loop_input.

That is, unless the caller explicitly asks for them.

Prevents conflict between e.g. the 'loop' option in img2 demuxer and
'loop' flag in AVCodecContext.

The build system doesn't use lib.exe any longer, and therefore this
can be simplified.

The copy regression test script is unused, bash-specific and did
not even work properly when it was originally committed.
