Name all ioctl references and make them match the ioctls that are documented. That will improve the cross-reference index, as it will have all ioctls and syscalls there. While here, improve the documentation, marking the deprecated ioctls, and making the non-deprecated ones more like the rest of the media book. Also, add a notice for ioctls that still require documentation. Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>
