ctlrscript: initial stub implementation

Browse source 
This commit adds a framework for TCC based scripting
of controllers. Given that TCC only compiles C, it is needed to translate
the C++ Event class instances to a plain C interface, which can then be
sent to the controller.

/** This is a controller using TCC as a backend, which reads .c files
* as "scripts", but compiles them on the fly and then hooks in the
* poll / handle event loop into the controller itself.
*
* It is designed to be a flexible way of prototyping support for any
* MIDI/HID devices. Once a controller file is concidered "finished",
* it may be sent as a pull request for inclusion in vanilla Luppp.
*
* As TCC is only a C compiler (as opposed to C++) this layer translates
* Luppps internal events (which are C++ classes) to native C structs,
* which can then be passed to the TCC compiled C backend. Ideally the
* Luppp internal event handling system would be ported to plain C,
* however this would also require significant effort, which does not
* seem worth the time at the moment.
