Based on the work by Martin Storsjö.

The decoder stores opaque buffers in the p_sys member of the picture
and the vout uses a callback from the decoder to render these
buffers. When the decoder flushes or closes, all the currently in
flight pictures (filled by the decoder but not displayed yet) need to
be invalidated. A mutex is required in order to prevent the vout from using
destroyed MediaCodec buffers.

In order to avoid a deadlock when exiting the decoder, a maximum number of polling
attempts was added in order to avoid blocking the decoder indefinitely if the vout
is not releasing output buffers anymore.

"NB, this is a temporary encoder only module until schroedinger
offers superior encoding quality than dirac-research"

"Schrödinger outperforms dirac-research in most encoding situations,
both in terms of encoding speed and visual quality."

Can still have unsent blocks.

(no fix as codec sends bad pts sequence)

1st header write can contain random values but that
triggers false positive on valgrind.

refs #10386
Still junk on bottom due to invalid plane->i_visible_lines

Can't use granule 0 as it means there's still no valid first sample
after processing packet.
Fix start gap on opus webradios.

Implement a function to load the Native Window API from the Android
library.  This API is needed by current vouts nativewindow and surface
and will also be needed by the opaque vout.
