Julien Isorce 80c6dd46a1 omxvideodec: use OMX_UseBuffer 
For example this allows the omx decoder to directly fill the
pixmaps coming from the video sink.

It only avoids a buffer copy when the decoder uses a pool provided
by a downstream element. So let's restrict this usage to situations
where the decoder decides to use a downstream buffer pool.

Tested with Tizonia/OMX.Aratelia.video_decoder.vp8
and with Bellagio/OMX.mesa.video_decoder.avc.

If it fails to setup buffers with OMX_UseBuffer the decoders
fallbacks to usual OMX_AllocateBuffer.

Also it allows to test on desktop the GstOMXBufferPool->other_pool
management which was previously only used in the OMX_UseEGLImage
case, i.e. on Rpi.
