9dc359d0c1 omxbufferpool: fix race when releasing input buffers
If buffers were released from the pool while
gst_omx_video_enc_handle_frame() was waiting for new buffers,
gst_omx_port_acquire_buffer() was never awaken as the buffers weren't
released through OMX's messaging system.

GQueue isn't thread safe so also protect it with the lock mutex.

3828d9769c omxbufferpool: fix early input buffer release
We used to track the 'allocating' status on the pool. It is used while
allocating so output buffers aren't passed right away to OMX and input
ones are not re-added to the pending queue.

This was causing a bug when exporting buffers to v4l2src. On start
v4l2src acquires a buffer, read its stride and release it right away.
As no buffer was received by the encoder element at this point, 'allocating'
was still on TRUE and so the the buffer wasn't put back to the pending
queue and, as result, no longer available to the pool.

Fix this by checking the active status of the pool instead of manually
tracking it down. The pool is considered as active at the very end of
the activation process so we're good when buffers are released during
the activation.

f108eeafde omxvideodec: don't import OMX buffers from downstream
We already have code configuring the encoder stride and slice height
when receiving the first buffer from upstream.
We don't have an equivalent when the encoder is exporting its buffers to the
decoder.

There is no point adding it and making the code even more
complex as we wouldn't gain anything by exporting from the encoder to
the decoder. The dynamic buffer mode already ensures 0-copy between OMX
components.

0996019c07 omxvideodec: prevent timeout when shutting down because of pending out buffers
The OMX transition state to Loaded won't be complete until all buffers
have been freed. There is no point waiting, and timeout, if we know that
output buffers haven't been freed yet.

The typical scenario is output buffers being still used downstream
and being freed later when released back to the pool.

d2f7e21ab9 omx: call gst_omx_buffer_unmap() when handling BUFFER_DONE
When using a input buffer pool, the buffer may be released to the pool when
gst_omx_buffer_unmap() is called. We need to have buf->used unset at
this point as the pool may use it to check the status of the pool.

{Empty,Fill}BufferDone is called from OMX internal threads while
messages are handled from gst elements' thread. Best to do all this
when handling the message so we don't mess with OMX threads and keep
the original thread/logic split.

3b92b22554 omxvideo{enc,dec}: stop calling shutdown() in change_state
This is no longer needed since we implemented close() vfuncs as the
encoder/decoder base class already take care of calling close() (which
is calling shutdown()) in its own change_state implementation.

We also move the shut down of the component from PAUSED_TO_READY to READY_TO_NULL.
By doing so upstream will have already deactivated the pool from the
encoder and so won't be preventing the OMX state change as the buffers
will all be released.

40ae47df5e omx: wait for flush complete and buffers being released when flushing
When flusing we should wait for OMX to send the flush command complete event
AND all ports being released.
We were stopping as soon as one of those condition was met.

Fix a race between FillThisBufferDone/EmptyBufferDone and the flush
EventCmdComplete messages. The OMX implementation is supposed to release
its buffers before posting the EventCmdComplete event but the ordering
isn't guaranteed as the FillThisBufferDone/EmptyBufferDone and
EventHandler callbacks can be called from different threads (cf 2.7
'Thread Safety' in the spec).

Only wait for buffers currently used by OMX as some buffers may not be
in the pending queue because they are held downstream.
