add a new GstMemory/GstAllocator based on dmabuf

Hello,

This patch add support of dmabuf (http://lwn.net/Articles/489703/) for
gstreamer.

I have create a new GstMemory/GstAllocator base on dmabuf which only mmap the
memory when requested.

To test it I have also modify v4l2src to make it export buffer file descriptor
instead of the classic mmapped buffer.

This command line make v4l export dmabuf fd buffers and the memory isn't mmap
in user space.
gst-launch-1.0 v4l2src io-mode=4 ! fakesink --gst-debug=dmabuf:5

while this force the memory to be mmap
gst-launch-1.0 v4l2src io-mode=4 ! fakesink dump=true --gst-debug=dmabuf:5
