As pointed by Christoph Egger <siccegge@stud.informatik.uni-erlangen.de>,

The config Option DVB_DIBCOM_DEBUG was dropped while removing the dibusb
driver in favor of dvb-usb in 2005. However it remaind existant at some
places of the kernel config.

Instead of just removing the debug capability, the better is to just remove
the bad dependency, making the modprobe function always visible.

Some (North American) providers use a non-standard mode called
"8psk turbo fec". Since there is no flag in the driver that
would allow an application to determine whether a particular
device can handle "turbo fec", the attached patch introduces
FE_CAN_TURBO_FEC.

Since there is no flag in the SI data that would indicate
that a transponder uses "turbo fec", VDR will assume that
all 8psk transponders on DVB-S use "turbo fec".

There's a currently-unused lgdt3304 demod driver, which leaves a lot to
be desired as far as functionality. The 3304 is unsurprisingly quite
similar to the 3305, and empirical testing yeilds far better results
and more complete functionality by merging 3304 support into the 3305
driver. (For example, the current lgdt3304 driver lacks support for
signal strength, snr, ucblocks, etc., which we get w/the lgdt3305).

For the moment, not dropping the lgdt3304 driver, and its still up to
a given device's config setup to choose which demod driver to use, but
I'd suggest dropping the 3304 driver entirely.

As a follow-up to this patch, I've got another patch that adds support
for the KWorld PlusTV 340U (ATSC) em2870-based tuner stick, driving
its lgdt3304 demod via this lgdt3305 driver, which is what I used to
successfully test this patch with both VSB_8 and QAM_256 signals.

A few pieces are still a touch crude, but I think its a solid start,
as well as much cleaner and more feature-complete than the existing
lgdt3304 driver.
