Massive code refactor en cours!

Less complain from compilers:
 - use nullptr instead of NULL
 - use types for event fields
 - explicit type casting added
Stop saving parameters of meta events in p1/p2 fields of SEvent.
callback_t now uses std::function, deprecating ICallback.

Not recommended for daily usage, or even testing: the code refactor
is still a work in progress.
