a bunch of smaller speedups to core functions

Browse Source 
*  make local functions "static"
* use fast_ int types where possible
* use native min/max instead of MIN/MAX macros. Macros evaluate each parameter TWICE!!
* adding __attribute__((pure)) and __attribute((const)) to help the compiler optimize
* ws.cpp: reduce max "live leds" in fastpath mode
