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:

b68d936ae0 Remove plugin specific static build option

--enable-static/--enable-shared toggle are sufficient.

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.

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.

527c218533 v4l2src: link against -lrt for clock_gettime() 
Need to explicitly link against -lrt for clock_gettime(), which
we don't get in the libs any more, because core moved the
gmodule-no-export-2.0 bit into Requires.Private.

Not required for newer glibc, but for older ones, so check for that.

8c5d8b52ea v4l2: ensure autogenerated files are created 
The tuner marshal and enumtypes are autogenerated, and they need
to be created before the compilation of gstv4l2tuner.c

This patch adds the automake instruction for ensuring the
autogeneration of those files previous the compilation.

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.

Original commit message from CVS:
this adds video4linux2 source and element plugins. The division in v4l2* plugins is the same as for v4l1 - i.e. an element, a src and a sink, but there won't be separate encoding plugins (like v4lmjpegsrc) - all functionality is (thanks to video4linux2) integrated in one plugin: v4l2src. v4l2sink is still to be done, that'll come later.
