Start moving the dvb specific code to ngene-dvb.c. Note that there is still
stuff in ngene-core.c which could potentially be moved out, but it will require
considerable reworking of the logic in order to continue to properly support
DVB while also being able to support transport streams coming from analog MPEG
encoders.

The current code assumes that channel zero is always a TS input, which would
result in an oops if the "one_adapter" modprobe option is 1 (which it is by
default) and the board in question has something else on channel zero (which
is the case for the Avermedia m780, which has it's analog input wired to UVI1)
The code now explicitly tracks the first adapter created and ensures that
other channels cannot accidentially be associated with a NULL adapter.
Also, eliminate what appears to be a typo where all of the channel parameters
are getting associated with stream zero's properties, which will work if you
happen to have a dual stream board with the exact same configuration, but if
they differ then the second stream is going to end up with the first stream's
configuration.

I changed the dma buffers to use allocated memory instead of stack
memory.
The reason for this is documented in Documentation/DMA-API-HOWTO.txt
under the section: "What memory is DMA'able?" That document was only
added a couple weeks ago and there are still lots of modules which
haven't been corrected yet. Btw. Smatch includes a pretty good test to
find places which use stack memory as a dma buffer. That's how I found
these. (http://smatch.sf.net).

A flag for detecting PSK_8, however, is missing.
This patch adds the flag FE_CAN_PSK_8 to frontend.h and implements
it for the gp8psk-fe.c and cx24116.c driver (apparently the only ones
with PSK_8). Only the gp8psk-fe.c has been explicitly tested, though.

Address a problem found in MythTV where if we are in digital mode, switch to

after switching back to digital mode gets dropped. This is because the au8522

With applications like MythTV, switching inputs results in closing the digital
side and then immediately opening the analog side. This exposes a race
condition where the dvb_frontend kernel thread powers down the chip and closes
the i2c gate even though we're in the middle of bringing up the analog part
of the chip (since the shutdown of the dvb_frontend kernel thread occurs
asychronously).
Introduce a construct to keep track of what mode we're in, and drop requests
to power down or management the gate if we've already switched to analog mode.
