For demod drivers, we want a single tuning function (set_frontend) to have
access to the properly constructed dvb_frontend_parameters structure, or
the cache values - regardless of whether the legacy or new API is being used.

This cuts down on redundant code in the demod drivers and ensures the
tuning parameters are consistent regardless of the API entry type.

After discussion the following changes were made:
1. Removed the typedefs in frontend.h, use structures.
2. In the frontend.h, remove the 16 command limit on the API and
   switch to a flexible variable length API. For practical reasons
   a #define limits this to 64, this should be discussed.
3. Changed dvb-core ioctl handing to deal with variable sequences
   of commands.

tune-v0.0.3.c is required to use this API, it contains the interface changes.

SET_TONE and SET_VOLTAGE were not previously implemented. Two options
existed. Either cut/paste from the previous ioctl handler into the
process_properties function, which is code duplication. Or, split
the current ioctl handler into it's two major pieces.

Piece 1, responsible for input validation and semaphore acquiring
Piece 2 the processing of the previous ioctls

and finally, a new third pieces where the array of properties
is processed, and can freely call the legacy ioctl handler without
having to re-acquire the fepriv->sem semaphore. This is a clean approach
and ensures the existing legacy ioctls are processed as they were previously
(but with an extra function call) and allows the new API to share code
without duplication.

This is an experimental patch to add a new tuning mechanism for
dvb frontends. Rather than passing fixed structures across the
user/kernel boundary, which need to be revised for each new modulation
type (or feature the kernel developers want to add), this implements
a simpler message based approach, allowing fe commands to be broken
down into a series of small fixed size transactions, presented
in an array.

The goal is to avoid changing the user/kernel ABI in the future, by
simply creating new frontend commands (and sequencies of commands) that
help us add support for brand new demodulator, delivery system or
statistics related commmands.

known issues:
checkpatch voilations
feedback from various developers yet to be implemented, relating
to namespace conventions, variable length array passing conventions,
and generally some optimization.

This patch should support all existing tuning mechanisms through the
new API, as well as adding 8PSK, DVB-S2 NBC-QPSK and ISDB-T API support.

With video_nr, vbi_nr and radio_nr being simple integers, it is not
possible to use these parameters on a system with multiple bttv
adapters (which happens to be my case.) video_register_device() will
always fail on the second and later adapters. Turn these parameters
into arrays, as many other V4L drivers are already doing, so that they
can be used on such systems.

Dont pass devptr in xc5000_attach, dont store it in xc5000_priv.
This pointer is passed into the tuner_callback function, which always
expects a pointer to fe->dvb->priv or i2c_adapter->algo_data.

This prevents future possible bugs in new drivers, such as using a "devptr"
other that the standard fe->dvb->priv in a DVB driver.

Prevent an OOPS if xc5000_attach was called by tuner.ko before being called by
the DVB adapter driver. The OOPS occurs when a digital tune request is made
after tuner.ko is unloaded.

When tuner.ko is unloaded, it takes the xc5000_config structure with it.

Rather than storing a pointer to the xc5000_config structure, just store the
if_khz and tuner_callback inside the xc5000_priv internal state structure.
