A previous change (v4l2-common: remove v4l2_ctrl_query_fill_std) broke
the handling of class controls in VIDIOC_QUERYCTRL. The MPEG class control
was broken for all drivers that use the cx2341x module and the USER class
control was broken for ivtv and cx18.

This change adds back proper class control support.

Both the MPEG-2 SVCD stream format and the MPEG-2 DVD stream format should
use an MPEG-2 PS container.  This makes it safe to stuff IVTV Private Stream 1
VBI packets in these stream types using the existing cx18 driver routines.

The cx18 private packet insertion code only expects to operate on an MPEG PS
when inserting private packets of sliced VBI data.  This patch keeps the cx18
driver from corrupting the MPEG TS or other non-PS stream types, in case the
user enables sliced VBI insertion for these MPEG stream types.

Convert GPIO line functions, such a audio routing and device resets, to
v4l2_subdevices.  This essentially completes the conversion of cx18 to the
v4l2_device/v4l2_subdevice framework.  No regression testing has taken place as
of yet.  Also an ivtv legacy bug with GPIO mux routing and going to/from radio
mode was commented, but not fixed.

This is a major perturbation to cx18 I2C device handling to convert it to the
v4l2_device/subdeivce framework.  This change breaks GPIO audio multiplexer
control for the time being.  It will be fixed in a coming change.

Added a new chip identifer to v4l2-chip-ident for the integrated A/V broadcast
decoder core internal to the CX23418.  Completed separation and encapsulation
of the A/V decoder core interface as a v4l2_subdevice.  The cx18 driver now
compiles and links again.

cx18: Use a known open task handle when setting stream CX2341x parameters
Sometimes, we might only have VBI or YUV stream open instead of an MPEG stream.
Let's make sure we use a valid task handle to perform the CX2341x control
settings.

cx18: convert driver to use video_ioctl2().  Pushed down ioctl debug

Due to a driver bug -EBUSY would be returned when attempting to setup an

Many thanks to Steve Toth from Hauppauge and Nattu Dakshinamurthy from
Conexant for their support. I am in particular thankful to Hauppauge
since without their help this driver would not exist. It should also
be noted that Steve did the work to get the DVB part up and running.
Thank you!
