V4L/DVB: ir-core: dynamically load the compiled IR protocols
Instead of hardcoding the protocols into ir-core, add a register interface
for the IR protocol decoders, and convert ir-nec-decoder into a client of
ir-core.
With this approach, it is possible to dynamically load the needed IR protocols,
and to add a RAW IR interface module, registered as one IR raw protocol decoder.
This patch opens a way to register a lirc_dev interface to work as an userspace
IR protocol decoder.
