- reworked i2c / gpio so not so hackerish and more in line with

  what Gerd is moving to

- allowed multiple instances of dst frontend.

- should handle terrestial cards correctly. Can mix and match
  ts204, new tuner packets, symbol rate types in tuner packets

- has more DST strings on i2c asic discovery (in dst_check_ci)

- can override card PCI id using card=0x68 for bttv driver. bt878
audio dma still hogs all cards it finds, but this is an interim
release to work towards fixing this

- put in rudimentary signal strength / snr. The scale factors
are not right. Should work for terrestial / satellite.

- Put in Dimitri's fix of not doing dst_enable after reciept of
the 0xFF ack, but allowing the asic to do this itself.
