078560e70a v4l2: use GstV4l2Error in gst_v4l2_open() 
gst_v4l2_open() is called by gst_v4l2_device_provider_probe_device(),
where the GstV4l2Object is created without an associated GstElement.

If gst_v4l2_open() fails, it raises a bus message, but without an
element, a precondition check fails on
gst_element_message_full_with_details() generating a crash if running
with fatal-warnings debug mode.

GstV4l2Error is a helper to raise error bus messages when it is
appropiated. This patch changes the direct bus messages to this
helper, and the elements will actually send the error message.

435c2acdc5 rpicamsrc: hypothetical fix for data pointer calculation 
mmal buffer header docs say data is valid for length bytes
from offset. In practice offset always seems to be 0 so
far though.

9588108d6e rpicamsrc: fix nal alignment of output buffers 
We claim output buffers are nal-aligned, but that wasn't
actually true: We would push out a partial nal in case
the nal doesn't fit into the max encoder-selected output
buffer size, and then the next buffer would not start
with a sync marker. That's not right and makes h264parse
unhappy.

Instead accumulate buffers until we have a full frame
(we can't rely on the NAL_END flag, it's always set).

Fixes #768

cab6585378 rpicamsrc: Expand frame timeout from 100ms to 500ms 
rpicamsrc on a normal rpi camera doesn't start up fast enough,

might be to have a longer timeout for the first frame, but
shorter once frames are running - but this quick fix will at
least make rpicamsrc work again.

b45e239128 rpicamsrc: RaspiCapture: use mmal_queue_timedwait() for buffer queueing 
If an external camera was disconnected, there were no feedback in an
application. It seems reasonable to wait on mmal_queue no longer than
100ms. If it's stuck we just return a FLOW_ERROR and let the application
decide what to do later.

ed893592ea rpicamsrc: Implement use-stc property to disable STC timestamps 
If use-stc=false, then rpicamsrc won't apply

relying on real-time timestamping by the
GStreamer clock. It means slightly less accuracy
and more jitter in timestamps, but might help on some
CSI inputs with broken timestamping.

ca61a76987 v4l2: Fix threading issues in orphaning mechanism 
The pool orphaning function was colling internal _stop() virtual function
implementation. This is not thread safe, as a private lock inside the buffer
pool is supposed to be held. Fix this by keeping delayed _stop() and orphaning
the GstV4L2Allocator instead (REQBUFS(0)).

Then, protect the orphaned boolean with the object lock for the case a buffer
is being released after we have orphaned the buffer. That would otherwise
cause a QBUF to happen while the queue is no longer owned by the buffer pool.
This boolean is otherwise used and set from the streaming lock, or after
threads have been stopped (final cleanup).

71204f2c3b v4l2bufferpoool: Fix requeueue after seek when importing 
When the buffer pool is importing buffer, it will requeue num_allocated on
streamon. As this value was not set for DMABuf import and USERPTR, no buffer
was queued  back.

83f60aea54 v4l2bufferpool: Only resurrect the right amount of buffers 
On streamon, we need to resurrect (queue back) some buffers, as during
flushign seek we'd endup with an empty queued. We initially started with
resurrecting as many as we could without blocking, but that miss-behaved with
dynamic CREATE_BUFS, causing the pool to grow dramatically. This was limited
by the number of allocated buffers, but this still tried to resurrect too many
buffers for the first run, as activating the pool will queued buffers.

In this patch, we calculte the missing detal in the queue and only try and
resurrect that amount of buffers.

85b9893e96 v4l2object: Only offer inactive pools and if needed 
Avoid offering a pool if it's not needed or if it's still active.
This works around the fact the we only have one pool in V4L2.

93b202b84e v4l2allocator: Don't do REQBUFS(0) on inactive allocator 
If the allocator is no longer active, it means the memory has already
been freed, calling REQBUF(0) would make no sense.

b8f1f2195e v4l2bufferpool: Avoid set_flushing warning 
The gst_buffer_pool_set_flushing() warns when that function is called
on an inactive pool. Avoid the warning by checking the state, this is
similar to what we do in gst_v4l2_object_unlock().
