Added code to cx88-blackbird.c to treat the VIDIOC_S_FREQUENCY ioctl
to stop mpeg stream before changing the frequency and restart it after.
It seems that the mpeg stream needs to be paused while changing the
channel frequency, otherwise the mpeg encoder enters into a bad state,
producing artifacts.

cx88-blackbird uses the same encoder firmware for the cx23416 chip that is
used by ivtv and pvrusb2.
This patch alters the driver to expect the cx23416 encoder firmware to be
located in the file, "v4l-cx2341x-enc.fw", instead of using
"blackbird-fw-enc.bin"

This patch removes all of the BLACKBIRD_API #define's, instead

The KWorld HardwareMpegTV XPert uses a multistandard tuner, tda8290 + tda8275.
Without checking the video standard in blackbird_probe, the encoder defaults
to PAL, even if the incoming video stream is NTSC. This patch checks the video
standard set by the cx2388x decoder, and sets the encoding height and frame
accordingly.
This patch is designed to only affect the KWorld HardwareMpegTV XPert.

Video_buf were concerned to allow PCI devices to be used as
video capture devices. This patch extends video_buf features
by virtualizing pci-dependent functions and allowing other
type of devices to use it.
It is still DMA centric, although it may be used also by
devices that emulates scatter/gather behavior or a DMA device

- This patch adds eeprom awareness for the Roslyn. In effect, the
blackbird will query the tuner V4L2_STD_xxxx definitions to determine
whether it's connected to a NTSC or PAL tuner. Based on that, various
default values will change for blackbird encoding.
- Fixes back panel SVIDEO/COMPOSITE with audio, work properly.
- Fixes a problem with lip sync issues, due to bad framerate vs
audio rate assumptions.
- Fixed a problem with the GPIO configuration in cx88-cards.
- Removed the comments in cx88-cards that made no sense.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!
