This fixes linking errors where variables cannot be correctly linked in from an external shared library such as with msvc (requires dllimport which is not used by libaom). Instead just call the function that returns the same variable.

some of the initial bits for RISC-V support.

Prevents desktop stutters caused by the change (specifically on KDE).

The packets delivered to this decoder are often decoded to more than
one frame and if the internal buffer packet is not unreferenced,
the decoder will still output frames derived from the old packet (from
before the flush).

This decoder may output multiple AVFrames for every AVPacket
passed to it, but after it has returned AVERROR(EAGAIN),
it is completely drained and there is no reason to flush it
at the end with a NULL packet. Furthermore, there is also no
delay in the common sense of the word.

Such fields can be seen as generally useful in cases where the
API user is not implementing custom AVIO callbacks, but still would
like to know if data is being read or written out, such as in case
data is being read from input but no AVPacket has been received yet.
Originally added as a private entry in commit
3f75e5116b, but its grouping with
the comment noting its private state was missed during merging of
the field from Libav (most likely due to an already existing field
in between).
Looking at 3f75e5116b, the field
was supposed to be private, but during merging the field and the
group that had the comment about it got separated.
Thus, move the actual privately utilized state of this variable
into the private FFIOContext. Additionally, name the private field
somewhat better, so that it does not get confused with the amount
of bytes written out.
