If the call to cx88_core_get returns a NULL value, it is dereferenced
by cx88_reset, and perhaps by cx88_core_put. Spotted by the Coverity
checker.

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

- static vars are equal to zero by default. Removed
unnecessary =0 from them, saving some data space;
- Fixed compiling against kernels bellow 2.6.13.

VIDEO_ALSA now actually means "enable ALSA modules". Both cx88 and saa7134
are covered by it (bt87x is disabled as it may conflict with snd_bt87x in
ALSA's tree), and it now defaults to "y".

Existing audio DMA uses conflict with cx88-alsa. This workaround disables
that code if cx88-alsa is being compiled

The audio distortion was apparently being caused by the high amount of
interrupts being generated. Increasing the buffer from 512 to 4096 seems
to fix it

It's still not perfect (lots of over and underruns), but there's now working
audio.
Dropped the videobuf queues (too geared for video...) in favor of a single
RISC databuffer, and changed the remaining code accordingly. And it works ;)

The module can now be removed and reloaded without problems, if the PCM
isn't opened. PCM cleanup is still missing.

Changed a few more things in the buffers and ALSA initialization code, but
still no luck. No IRQ activity yet, even with the IRQ mask fixed.
