27310365d5 v4l2: Add Video Encoder support 
This implements H264 encoding support using generic V4L2 interface. It is
reported to work with Samsung MFC driver, IXM.6 CODA driver and
Qualcomm mainline Venus driver. Other platform should be supported as
none of this work is platform specific.

The implementation consist of a GstV4l2VideoEnc base class, which
implements the core streaming functionality. This base class is implemented
by GstV4l2H264Enc class that implements the caps negotiation specific to
H264 profiles and level. This implementation supports hardware with multiple
H264 encoder. Though, to make it simplier to use, the first discovered H264
encoder will be named v4l2h264enc. Other encoder found during discovery will
have a unique name like v4l2video0h264enc.

This work is the combined work of multiple developpers in the last 3
years. Thanks to all of the contributors:

67c2b93106 v4l2: fix v4l2 probe build error 
A typo in gst_v4l2_probe_and_register() caused a build error when building
with --enable-v4l2-probe. Fixing it.

gstv4l2.c: In function 'gst_v4l2_probe_and_register':
gstv4l2.c:150:25: error: 'struct v4l2_capability' has no member named 'capabilitites'
       device_caps = vcap.capabilitites;

4b16b16aaf v4l2: use opened device caps instead of physical device ones 
The same physical device can export multiple devices. In
this case, the capabilities field now contains a union of
all caps available from all exported V4L2 devices alongside
a V4L2_CAP_DEVICE_CAPS flag that should be used to decide
what capabilities to consider. In our case, we need the
ones from the exported device we are using.

f19cfbda96 v4l2: Add v4l2sink element 
This also does the following changes:
(1) pull the bufferpool code out into gstv4l2bufferpool.c, and make a
    bit more generic so it can be used both for v4l2src and v4l2sink
(2) move some of the device probing/configuration/caps stuff into
    gstv4l2object.c so it does not have to be duplicated between
    v4l2src and v4l2sink

Fixes bug #590280.
