Initiated v4l-apps/lib V4L2 functions

From: Mauro Carvalho Chehab <mchehab@infradead.org>

- Created v4l2_driver.c with some basic functions to:
	. Enum STD, INPUT and FORMAT
	. GET/SET STD and INPUT
	. GET PARAM
- ioctl-test reverted back to a simple "brute-force" all ioctl call;

- driver-test created to:
	. test V4L2 kernel drivers;
	. implement all functions provided by v4l2 library

- driver-test should grow following the changes at v4l2-apps/lib
