When there are no more free buffers, then buffers are stolen from the
predma queue. Buffers should be stolen from the head of that queue (which
is where the most recently added buffers are) and all buffers belonging
to a frame should be stolen. Otherwise 'half-frames' would remain in the
queue, which leads to ugly playback and complete sync failure for YUV
buffers.

The CX2341X_ENC_INITIALIZE_INPUT firmware call requires careful handling,
otherwise the computer can freeze or the top-third of the screen can start
flickering. This patch ensures that CX2341X_ENC_INITIALIZE_INPUT is called
at the right time and in the right way.

In addition the stop capture handling was improved so that the last pending
DMA transfer is also processed. Otherwise this would be the first data that
arrived when a new capture was started which is not what you want.

When changing channels the audio has to be muted. This is done 
by calling CX2341X_ENC_MUTE_AUDIO and by muted the audio input. 
The latter is not necessary and is now removed.

The firmware is now loaded when the driver is actually used for the first
time. This allows the driver to be compiled in-kernel instead of as a module.

Using udma yuv causes the driver becomes locked into that mode. This prevents
use of the mpeg decoder & non-udma yuv output. This patch clears the
operating mode when the device is closed.

Due to a documentation bug (the type mask is 3 bits long, not 2) the wrong
frame types were filled in: the B and P frame types were swapped.

This bug also hid a second bug: when a capture is stopped a last entry is
written into the pgm index buffer with internal type 0, denoting the end
of the program. This entry wasn't ignored, instead it was accidentally
returned to the caller as a P frame.

While decoding (MPEG or YUV) is active or when VBI output is in use, then
do not clear the VBI output of the saa7127. Only after the last user is
gone can we clear it.

This fixes the case where playback was stopped, another channel was chosen
and playback was restarted, while /dev/vbi16 was used to set the WSS
(widescreen) setting. Without this fix the WSS was reset on every stop
instead of just keeping the last value.

It took three core maintainers, over four years of work, eight new i2c
modules, eleven new V4L2 ioctls, three new DVB video ioctls, a Sliced
VBI API, a new MPEG encoder API, an enhanced DVB video MPEG decoding
API, major YUV/OSD contributions from Ian and John, web/wiki/svn/trac
support from Axel Thimm, (hardware) support from Hauppauge, support and
assistance from the v4l-dvb people and the many, many users of ivtv to
finally make it possible to merge this driver into the kernel.
Thank you all!
