Currently the saa7134 chips only have mute support for the TV input.

Cards with mute from external audio muxes are already fine on the
other inputs and some recent tuners mute at least the radio on exit.
But these mostly hybrid tuners are not fully backward compatible, since
they must power down and mute regardless.

For some included above, the MD7134 knows several, to switch on mute/automute
to the TV input is functional and backward compatible for the applications,
except that the tuners with tda9887 always mute on exit.

This change adds support for 4 extra keys on the remote currently being
shipped by leadtek with their "WinFast TV2000 XP/Expert" and
"WinFast PVR2000" cards. The remote P/N seems to be Y04G0033 and
you can see a picture of it here: http://lespinasse.org/y04g0033.jpg

The extra keys are at the bottom and are labeled MCE +VOL, -VOL, +CH, -CH.
I chose to map them to the F21-F24 keycodes, following the precedent of
ir_codes_gotview7135[], so as to differentiate these 'MCE' keys from the
other +VOL, -VOL, +CH, -CH 'arrow' keys higher up on the remote.

s-code tables are related to IF frequency used for video demodulation.

The s-codes for analog are automatically loaded, according with video standard.
However, for digital, they will depend on the IF of the demoduler chip. IF of
the demoduler.

Before this patch, only a few IF's where possible to use. This patch allows
selecting any IF defined at firmware file.

Since check_firmware is called via analog or digital set freq routines, move
type selection to those routines. This avoids having several if's at the code,
and simplifies the source code.

A sideback effect is that implementing radio and other dvb types will become
simpler.

First the saa7134_initdev waits between saa7134_hwinit1

some hardware probably needs this.

Call saa7134_irq_video_signalchange in .resume like in saa7134_resume to make
saa7134_resume mirror perfectly the saa7134_initdev although
this call isn't strictly necessary in the saa7134_initdev,
but it won't harm anyway.

On some cases, xc2028/xc3028 wents into "turn off" mode. It seems that this
happens when very weak signals are tuned. To solve this, specific standard
reaload were done previously. Christopher patches changed this behavior to a
complete firmware reload.

This patch removes the hack. A much cleaner solution for this trouble is just
to sent a xc2028/3028 software reset.

xc3028 can be used on some DTV only designs (for example, DVB-S boards). Before
this patch, a DTV only board would need to call set_tuner_config callback.

This patch allows to optionally pass a xc3028_ctrl parameter, via xc3028_config
struct, fully initializing the driver for DTV.

Xc2028.3028 has two type of firmwares: audio-standard specific ones and
baseband MTS firmwares. MTS firmwares provide stereo decoding for 6 MHz
BTSC/EIAJ and for monoaural audio decoding on 8 MHz firmwares.

It seems that the option to use MTS or a standard-specific audio decoding
depends on the way xc2028/3028 is connected.

Instead of wasting 32 (or 64 bits) to signalize if the driver needs to use MTS
firmware, this patch converts it to a bitfield that can be shared with other
proprieties of xc2028/3028.

There are at least three variants of the DViCO FusionHDTV DVB-T NANO that
share the same USB device ID.  The first (ZL10353 w/ firmware in ROM) is
already supported; the latter two both require firmware and have either
an MT352 or ZL10353 demodulator, and have a different IR receiver from the
first.

This introduces a new identify_state that can tell the difference between a
"warm" device which is running the embedded firmware, and a "cold" device
that needs us to upload firmware to it before it will work.  We patch the
uploaded device ID (like we do for other bluebird devices) to make it easy
to identify the particular device variant when it reattaches.

NB: These devices use a different firmware file from previous bluebird
    devices.  You need a new firmware file to make this work.

Define a list of valid "firmware types" for each combination of BASE,
DTV and SCODEs.  By masking the appropriate firmware bits off we can
just use one "type" for the firmware searching and also flag when we
are looking for a BASE, DTV or SCODE type firmware.  This makes it
much easier to track if we need to change device modes or flash an
individual firmware part.

Add a structure to remember what firmware properties we have.  This
contains the currently loaded/wanted  base firmware (type), video std
(id), video std requested (std_req), scode file and number in use.

Incorporate said structure into the tuner private data.

When checking whether the current firmware needs to be reloaded, first
figure out exactly what "type" of firmware we want (base, std and
scode), and then proceed to load the appropriate matching base,
std-specific and scode records iff there are any changes required.
This removes guesswork from the process because we no longer need to
individually code a check for every tuning parameter's interactions.
