irmp: introduce (part of) upstream IRMP sources

Introduce source files and documentation from the GPL'ed IRMP project.
Commit those files which represent the IRMP core logic (detection of
IR frames), and reference the project's homepage for the remainder.
These files correspond to

  svn://mikrocontroller.net/irmp r191
