After studying many hours worth of register dumps of MT352 and ZL10353 fed
with identically damaged RF signals I have made an educated guess at which
registers contain the AGC level, bit error rate and uncorrectable error
count values.
Implement the IOCTLs that return these values to userspace.

Force parallel transport stream output on the ZL10353 attached to a
bluebird device.
Addresses the problem where a frontend lock was observed, but no MPEG
transport data was received.

V4L/DVB (4028): Change dvb_frontend_ops to be a real field instead of a pointer field inside dvb_frontend

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.
