Consolidate timeout handling across platforms (#379)

Add Fl_Timeout class

Move platform independent code of Fl::wait() to main part

- basic timeout handling
- Fl::run_checks()
- Fl::run_idle()
- Fl::idle()
- waiting time calculation (next timeout)
- remove platform dependent "screen driver" stuff
