rc-core: feature parity with LIRC

The following patchset provides most of the features necessary for parity with
the LIRC subsystem that rc-core is intended to replace.

Most importantly, a chardev is provided which can be used to control RC hardware
using read (RX), write (TX) and ioctl (setting RX/TX parameters).

The patchset still needs further testing and I am well aware that patches will
be necessary to the current userspace tools as well. However, I'd like to get
the discussion started on whether the API needs any changes before I invest more
time in testing and patches to other tools.

Code review is welcome but the most important part is the userspace<->kernel
interface (i.e. the read/write/ioctl interface).

Comments?
