fd13e9e96d Implement V4l2 Allocator 
This goal of this allocator is mainly to allow tracking the memory.
Currently, when a buffer memory has been modified, the buffer and it's
memory is disposed and lost until the stream is restarted.

409cccb477 v4l2object: Workaround decoder that set num_planes to 0 in the format 
Some well known decoder wrongly set num_planes to 0 in their format instead of
one. In this case we would endup with no size when deciding buffer allocation.

0028de808b v4l2: Probe for CREATE_BUFS in order to correctly set pool min/max 
In order to correctly set the pool min/max, we need to probe for CREATE_BUFS
ioctl. This can be done as soon as the format has been negotiated using a
count of 0.

8d6e72a299 v4l2: Move capture eos handling in _process() 
Now that we might be copying out buffer (e.g. downstream don't support video
meta bug we need it) we need to move the EOS handling inside the process
method.

leading to wrong values in GstVideoMeta.

a8e81bd81e v4l2: Expose RGB32 formats with and without alpha

format as ARGB and BGRA as long we can deterministically set the alpha padding
value.

36dfdff84c v4l2object: Ensure video and crop meta are enabled if needed 
In certain cases we cannot live without video meta and/or crop meta
being enabled in our internal buffer pool. Ensure this is always the case,
regardless of having support for allocation query.

a8024fef04 v4l2videodec: Check that pool where allocated before flushing them 
Upon error, the pools might not have been allocated yet, hence we should not
try and flush them (even though we still want to make sure the processing thread
is fully stopped).

6196026c76 v4l2bufferpool: Enforce activation outside of process

2f00119e3b v4l2bufferpool: Use obj->n_v4l2_planes for correct number of planes 
Buffer pool was guessing wrongly the number of planes rather
then reading the value from obj->n_v4l2_planes. This was causing
format YU12 (I420) to fail upon check.

f3ce6fd25b v4l2object: Fix handling of contiuous vs non-contiguous support 
The complex mechanic to try and choose the right thing did not work. Instead,
simply probe the non-contiguous format first and then the contiguous one.
This is in fact very low overhead, as there is a relatively small number of
pixel format supported by each devices.

70e7868f18 v4l2object: Rename setup_format() method into acquire_format() 
The setup_format() was confusing since it does not set anything, in fact
it reads the setup from the driver and save it.

b5dde037b4 v4l2object: Fail cleanly if pixel format is unkown or not raw video 
Certain decoder has been found to not choose a format automatically. Running
v4l2videodec on these would assert. This patch will make it fail cleanly
instead.

7e379e8fff v4l2videodec: Clear the input state pointer after unref 
If caps are set again, we have a risk od returning from set_format with a
input_state pointing to dead memory. Clearing the pointer after unref fix
this issue.

7101c4341a v4l2videodec: handle stop being called without flush 
Uppon certain downstream error, stop() is called without a flush(). This mean that
the streaming thread may still be running even though unlock has been called.
Now calling flush to reset the decoder state if we are processing.
