5b1c0a4cfd osx: Make OSX version checks more consistent
And especially also consider update versions, e.g. 10.5 with updates
will be 1051 or similar and thus bigger than MAC_OS_X_VERSION_10_5 but
still won't have the API we want to use.

303cec48db v4l2: refactor by emulating one v4l2_plane in non-MPLANE mode
so that the buffer informations can be retrieved the same way
in both MPLANE and non-MPLANE mode.

61ae84b50d v4l2: add support for multi-planar V4L2 API
This api is in linux kernel since version 2.6.39,
and present in all version 3.

The commit that adds the API in master branch of the
linux kernel source is:
f8f3914cf9

v4l2 doc: "Some devices require data for each input
or output video frame to be placed in discontiguous
memory buffers"

There are newer structures 'struct v4l2_pix_format_mplane'
and 'struct v4l2_plane'.
So the pixel format is not setup with the same API when using
multi-planar.

Also for gst-v4l2, one of the difference is that in GstV4l2Meta
there are now one mem pointer for each maped plane.

When not using multi-planar, this commit takes care of keeping
the same code path than previously. So that the 2 cases are
in two different blocks triggered from V4L2_TYPE_IS_MULTIPLANAR.

8e43c0ec9e v4l2: Optimize negotiation by removing the query filter
As cameras tend to have a quite specific set of capabilities (specific
framerates for each resolution), getting the peer caps filtered by our
probed caps can cause a big increase in the caps size which slows down
things quire a bit.

As for negotiation v4l2 iterates through the caps of the peer to find the
first intersection with the probed caps, getting the fully expanded
intersection of capabilities is not useful.

Using the same testcase as for bug #702632, adding this patch on top of
the patches suggested there speeds up getting the inital frame from
around ~14-15 seconds to around ~3-4 seconds.

0769a78dd1 v4l2: iterate controls with V4L2_CTRL_FLAG_NEXT_CTRL if possible
In v2.6.18 control classes where added to the v4l2 API.
Iterating over CIDs starting with V4L2_CID_BASE will only find controls for
the first control class.
By iterating with V4L2_CTRL_FLAG_NEXT_CTRL all controls are found.

This is necessary to make controls from other control classes available in
the extra-controls property.

If V4L2_CTRL_FLAG_NEXT_CTRL is not defined at compile time or not supported
at runtime then the old mechanism for iterating is used.

3417a791ac v4l2: call VIDIOC_REQBUFS with count = 0 in pool_finalize
Without this the following sequence fails:

- set_caps()
  - object_stop() (does nothing)
  - set_format() -> VIDIOC_S_FMT
- set_config() -> VIDIOC_REQBUFS with count = N
- set_caps()
  - object_stop()
    - pool_finalize()
  - set_format() -> VIDIOC_S_FMT => EBUSY

Usually the pool is started after set_config(), in which case object_stop()
will result in a pool_stop and therefore VIDIOC_REQBUFS with count = 0 but
that is not guaranteed.
Also calling VIDIOC_REQBUFS with count = 0 in pool_finalize() if necessary
fixes this problem.

496995a7d5 v4l2: rework sink buffer refcounting
This is a followup patch for #700781, which is not quite correct.
The buffer handling is quite complicated here.
The original code intended to the the following:

- gst_v4l2_buffer_pool_process() calls QBUF and adds the buffer to the
  local list.
- The sink calls gst_buffer_unref() which returns the buffer to the pool
  but not the 'free list'.
- Some time later DQBUF returns the buffer and
  gst_v4l2_buffer_pool_release_buffer() puts in on the 'free list'.

If the buffer must be copied then (parent_class)->acquire_buffer() is
called directly to keep the buffer in the pool.

This has two problems:
1. If gst_v4l2_buffer_pool_release_buffer() is called before the buffer is
   returned to the pool, then the buffer is put on the 'free list' twice.
   This can happen if a reference to the buffer is kept outside the sink,
   of if DQBUF returns the buffer, that was just queued with QBUF.
2. If buffers are copied, then all buffers are in the pool at all times. As
   a result gst_v4l2_buffer_pool_stop() and gst_v4l2_buffer_pool_dqbuf()
   can access pool->buffers at the same time, which can lead to memory
   corruption.

The patch for #700781 fixes those problems, but with the side effect that
there are always buffers outside the pool (because they are queued) and
the pool is never stopped.
This patch fixes this by releasing the reference to the buffer after
handling it (to avoid problem 2.) so it can be returned to the pool.
gst_v4l2_buffer_pool_release_buffer() is only called if the buffer is
already in the pool (to avoid problem 1.).

3340baa374 Revert "v4l2: disable renegotiation"
This reverts commit d1b26e1d59.

This causes the initial negotiation to never happen if a reconfigure
event is received after gst_base_src_start_complete() but before the loop
starts.

14300e5805 v4l2: free all queued buffers
Don't just loop over the first num_queued buffers but loop over
all the buffers and check if they need to be freed. It is possible that
not all buffers are queued and then the entry in our array will be NULL.
Those buffers that are not queued were freed in stop().

e29ab42922 v4l2: Add support of dmabuf
v4l has add a new IOCTL to export a buffer by using dmabuf.
This patch allow to use this new IOTCL if it has been defined in videodev2.h
I introduce a new IO mode (GST_V4L2_IO_DMABUF) to enable this way of working.
