In some cases when using VSB, the AGC status register has been known to
falsely report "no signal" when in fact there is a carrier lock. The
datasheet labels these status flags as QAM only, yet the lgdt330x
module is using these flags for both QAM and VSB.
This patch allows for the carrier recovery lock status register to be
tested, even if the agc signal status register falsely reports no signal.
Thanks to jcrews from #linuxtv in irc, for initially reporting this bug.

Update the SNR calculations to use the new dvb_math log function, and add
SNR calculations for all supported modulations for both lg dt3302 and dt3303.
The QAM equations don't appear in the dt3302 datasheet, so the ones from the
dt3303 datasheet were used.
SNR returned is the actual value in dB as 8.8 fixed point.
Reporting of real signal strength isn't supported, so rather than return 0,
which confuses some software and users, a re-scaled SNR value is returned.

The dvb_frontend_ops is a pointer inside dvb_frontend. That's why every demod-driver
is having a field of dvb_frontend_ops in its private-state-struct and
using the reference for filling the pointer-field in dvb_frontend.
- It saves at least two lines of code per demod-driver,
- reduces object size (one less dereference per frontend_ops-access),
- be coherent with dvb_tuner_ops,
- makes it a little bit easier for newbies to understand how it works and
- avoids stupid mistakes because you would have to copy the dvb_frontend_ops
always, before you could assign the static pointer directly, which was
dangerous.

I recently picked up my older work to remove unnecessary #includes of
sched.h, starting from a patch by Dave Jones to not include sched.h
from module.h. This reduces the number of indirect includes of sched.h
by ~300. Another ~400 pointless direct includes can be removed after
this disentangling (patch to follow later).
However, quite a few indirect includes need to be fixed up for this.
In order to feed the patches through -mm with as little disturbance as
possible, I've split out the fixes I accumulated up to now (complete for
i386 and x86_64, more archs to follow later) and post them before the real
patch. This way this large part of the patch is kept simple with only
adding #includes, and all hunks are independent of each other. So if any
hunk rejects or gets in the way of other patches, just drop it. My scripts
will pick it up again in the next round.

Most of the patch is whitespace cleanup, but more importantly, this patch
checks to see whether a callback is set before calling it. On cx88 boards
(currently the only boards using lgdt330x in 2.6.13) every callback is set.
However, newer drivers currently in development leave a callback undefined,
and lgdt330x must not call it if it isn't defined.

Rename lgdt3302 to lgdt330x, to make way for the addition of lgdt3303
support in future revisions.
I am changing the name of this module now so that hopefully the name will
be changed before the release of 2.6.13 ... It wouldn't make sense to
release 2.6.13 with the name lgdt3302 in it, which will only be renamed to
lgdt330x in later versions.
