Implement new method for doing integer range checking, so that we can
more intelligently range-check radio and tv ranges at once.

In the previous patch we exploited the get_{min,max}_value facility to adjust
min/max allowable frequencies on the fly, depending on tuner mode.
Unfortunately, this facility was not used inside the *sym_to_val() function
that translates what we echo to sysfs, which means we got an -ERANGE despite
asking for a frequency between what we read to be min/max.
This patch corrects this small omission.

The internal control implementation in the pvrusb2 driver normally
encodes integer range limits using literal values in a const
structure. This change adds two function pointers, which if not null
will be called through in order to determine integer min / max
values.

Implement V4L2 driver for the Hauppauge PVR USB2 TV tuner.
The Hauppauge PVR USB2 is a USB connected TV tuner with an embedded
cx23416 hardware MPEG2 encoder. There are two major variants of this
device; this driver handles both. Any V4L2 application which
understands MPEG2 video stream data should be able to work with this
device.
