Remove the obsolete VIDIOC_G_MPEGCOMP and VIDIOC_S_MPEGCOMP ioctls from
the V4L2 API as per the removal schedule (October 2007).

v4l2_driver.c:v4l2_enum_stds: erroneously always returns failure
because errno is +ve, needs inverting for use as a v4l error code.
The diff command actually produced patched for two fixes; I separated
them manually into these two reports.

bttv driver presents a non-compliance: When S_FMT is called, pix.sizeimage reports
a different size than when QUERYBUF is called, for the same S_FMT.
The current code can work fine with this non-compliance, but an error should be
reported.
Those are the reports from bttv driver, by running driver-test:
FMT SET: 640x480, fourcc=YVU9, 640 bytes/line, 345600 bytes/frame, colorspace=0x00000000
<snip/>
QUERYBUF: 00:00:00.00000000 index=0, type=video-cap, bytesused=0, flags=0x00000000,
field=any, sequence=0, memory=mmap, offset=0x00000000, length=348160
TIMECODE: 00:00:00 type=0, flags=0x00000000, frames=0, userbits=0x00000000
QUERYBUF: ERROR: VIDIOC_S_FMT said buffer should have 345600 size, but received 348160 from QUERYBUF!

Add capabilities to the library and to the driver to receive video streams.
Library will use a callback, called every time a new buffer is reported by
dqbuf.

There is a non-compliance on video-buf implementation about calling REQBUFS
with count=0. According with API, this should free all buffers, but video-buf
returns, instead, -EINVAL.

This method requests buffers and maps it into a mmaped memory.
Still under testing. Still need other stuff to make stream to work.

- Better presentation of version
- Make v4l2_enum_fmt generic for all types
- Added v4l2_gettryset_fmt_cap to GET/TRY/SET fmt on capture
- driver-test now sets a video format

- 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

Fix the copyright lines in the v4l2 library. Also explicitly add
the Nathan's SOB for frequency.c.
