This avoids issues if there's more than one sentinel added
to a FIFO at the same time, since the FIFO is built as a
linked list.

Also use a custom buffer flag to mark sentinel buffers, to
avoid issues if a codec would set the EOS flag on returned
input buffers.

If there's a sentinel buffer in the queue, don't count it,
but wait until the right number of buffers have been freed.

These aren't used by the vlc omxil code, but might be used by
other omxil clients that can use the vlc iomx wrapper.

This isn't used by the vlc omxil module, but can be used by other
applications using the same iomx wrapper library.

This should fix Yamaha ADPCM in MKV

Not sure if this is a driver bug or a limitation.

This simplifies the code, and allows resizing non-standard blocks.

Close #6619

Don't use sys->csa, prefer to use the local variable

macosx: prevent intermittent crashes on quit by releasing the main window later, since libvlc can try to access it as long as it is alive

(regression from 855f0b7d)

Also fix huge memory leak in v4l2 access (buffers never released).

Close #6598

However, we still cannot select the full scale.

Close #6603 and #6602

In case of pure access:
 - use correct access_sys_t type,
 - remove unused parameters.

Especially fix memory leaks on error.
