f3ecbeb577 v4l2bufferpool: Get number of allocated buffers from allocator 
The value of num_allocated buffer would get confused when
buffer are being discarded.

b2dab42ce8 v4l2allocator: Fix libv4l2 support 
Need to include config.h, otherwise we endup directly using the
ioct/mmap/munmap calls and need to vall v4l2_munmap.

428d63c2e5 v4l2allocator: Set the flags on the object 
We where not setting the probed flags on the allocator, which mean even if
CREATE_BUFS was supported on some driver, it would endup being ignored.

815c9b7d35 v4l2bufferpool: Acquire cannot return a buffer from another pool 
Return a buffer from an otherpool has unwanted side effects that lead to leaks and
prevents deactivating the pool. Instead, we change the _process() API so it can
replace the internal buffer with the buffer from the downstream pool. This implied
moving from _fill() to _create() method in the src.

f13331e928 v4l2bufferpool: Sanetize buffer refount handling 
Buffer refcounting is a bit hard, because of the duality between CAPTURE and
OUTPUT mode. In the long term, we should consider having two seperate pool
instead of this mess. At least state should be better kept this way.

74a64be001 v4l2-allocator: Add S to REQBUFS/CREATE_BUFS enum 
All enum that has REQBUFS and CREATE_BUFS where missing S, which was
confusing since they are supposed to match with associcated ioctl name. This
also fixes the yet unused CAN_REQUEST flag check.

7b00d7ac46 v4l2allocator: Guaranty queued state integrety 
Because of the buf in videobuf2, dqbuf may leave the DONE flag being,
which would implied that the buffer is queued. As this has been broken
for 4 years, simply guaranty the state flags integrity when doing
qbuf/dqbuf.

cf6c7e9846 v4l2bufferpool: Do not pre-configure the pool 
Pre-configuring the pool is error prone, since it may hide a configuration failure and
endup with a pool that is not configured the way it should (e.g. no video meta, wrong
queue size, etc.)

db3d2f35f0 v4l2bufferpool: Early catch short allocation

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.
