[PATCH] v4l: bttv driver update

[PATCH] v4l: bttv driver update

 * the usual pile of tv card database updates.
 * various signed/unsigned fixups (fix gcc 3.3 warnings)
   and releated cleanups (use ARRAY_SIZE macro, ...).
 * moved some code which can be shared with the new,
   upcoming cx2388x driver to a separate module.
 * split the irq handler into smaller functions.
 * some new features (field rate capture support for example).
 * simplified i2c code a bit by removing redundant
   bookkeeping of attached i2c clients.
 * merged i2c changes back into my tree, there are some no-op
   changes due to this.
 * various other bugfixes.
 * fix build failure with CONFIG_FW_LOADER enabled
