Some IR remotes have a directional pad or other pointer-like thing that
can be used as a mouse. Make it possible to decode these types of IR
protocols in BPF.

It might also be possible to support non-button devices such as analog

Hi,
Again thanks for a thoughtful review. This will definitely will improve
the code.

nderway to extend ir-keytable to have an extensive library
of bpf-based decoders, and a much expanded library of rc keymaps.
Another future application would be to compile IRP[3] to a IR BPF program, and
so support virtually every remote without having to write a decoder for each.

Add support for BPF_PROG_IR_DECODER. This type of BPF program can call
rc_keydown() to reported decoded IR scancodes, or rc_repeat() to report
that the last key should be repeated.
