The commands to start / stop USB streaming for an analog device are
fairly standard, owing to the fact that all supported devices
apparently started from the same common reference design. However
with digital mode, the commands seem to vary by vendor. This change
makes that variance more explicit. It also cleans up a related
problem for OnAir devices which prevented digital mode from working at
all.

Numerous places in the driver need to issue simple commands to the FX2
microcontroller (e.g. only 1 or 2 bytes, no reply needed). Previously
each place that did this, had to take lock, set up a central buffer,
and call the function to perform the handshake. This change puts
these steps into a single spot. This also has the effect of removing
the need to mess with the control lock from numerous places in the
code.

Implement a mechanism in the pvrusb2 driver for gathering statistics
on the stream buffering, including bytes transferred, buffers handled,
buffers in flight, etc. This is useful for debugging certain classes
of streaming issues and for determining if the buffer pool size is
generally correct for the driver.

Move pvr2_dvb_adapter usage out of the pvrusb2 driver core - it's
really private to the pvrusb2-dvb module and nothing outside of the
dvb implementation should care about it. Creation / destruction of
the pvr2_dvb_adapter instance is now contained entirely within
pvrusb2-dvb.c.

In the end we'd like the dvb interface to always be present - even for
analog devices (via the mpeg encoder). However right now pvrusb2-dvb
won't operate correctly if the hardware doesn't have a digital tuner,
so don't initialize the DVB interface unless we know we have a digital
tuner.

Rather than making an explicit call to tear down the pvrusb2-dvb
module, use the callback in the pvr2_channel structure. This has the
advantage that now tear-down only happens when it makes sense. The
previous implementation had scenarios where it was possible for the
tear-down call to happen without a prior initialization.

Eliminate the need for a separate pvr2_dvb_fh; since in the DVB
context there can only ever be a single instance then there is no need
for a separate instance to handle streaming state. This simplifies
the module. Also move streaming start/stop out of the feed thread and
into the driver's main context - which makes it possible for streaming
start up failures to be detected by the DVB core.

The pvrusb2-dvb feed thread cannot be allowed to exit by itself
without first waiting for kthread_should_stop() to return true.
Otherwise the driver will have a dangling task_struct context, which
will cause a very nasty kernel oops.

Add basic framework for the DVB API. This is enough to control the
tuner & demod of the digital frontend, but the stream & buffer handling
is still missing.
Additional note from Mike Isely <isely@pobox.com> - also, since these
changes are still very experimental arrange for DVB changes to be
compiled in via new CONFIG_VIDEO_PVRUSB2_DVB option, for now.

Currently the pxa-camera driver has a bug, visible when the user requests
more than 2 video buffers. When the third buffer is queued, it is not
appended to the DMA-descriptor list of the second buffer, but is again
appended to the first buffer. Fix it.

This reqires a different setup of the clock PLL.

values for the boards.

This patch fixes several issues on SCODE:
1) The extracting tool weren't generating the proper tags for SCODE. This
has almost no effect, since those tags shouldn't be used;
2) DIBCOM52 were using a wrong IF. It should be 5200, instead of 5700;
3) seek_firmware were wanting an exact match for firmware type. This is
wrong. As result, no SCODE firmware were loaded;
4) A few files were including the wrong file for seeking demod firmwares;
5) XC3028_FE_DEFAULT can be used, if user doesn't want to load a firmware.
However, this weren't documentated. This feature require more testing.
