V4L/DVB: firedtv: correct version number and current/next in CA_PMT

The version number in the CA_PMT message sent to the hardware was
alwaysed set to zero. This could cause problems if the PMT would
change during decryption of a channel since the new CA_PMT would have
the same version number as the old. The version number is now copied
from the original PMT.

V4L/DVB: cx88: increase BUFFER_TIMEOUT to 2 seconds

When temporarily there is no video signal, sometimes it takes more than 0.5
secs for the cx88 chip to generate a single frame. If a dma timeout occurs
during recording, it confuses the recording application (at least mencoder)
and the recording stops.

Since there is already an #if 0 for 2 seconds buffer timeout in the code
at the -hg development tree, re-enabling that seemed the most simple
solution.

V4L/DVB: au8522: fix race condition in switching from digital to analog mode

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.

Previously, there were no sync between video buffer filling and received

- Sometimes, there were no available continuos block of about 1 MB;
- Image weren't not properly updated, since parts of the URBs aren't
