- headers use the endpoint_t in syslib.h and the implmentation was using int
instead. Both uses endpoint_t now
- every variable named like proc, proc_nr or proc_nr_e of type endpoint_t has
name proc_ep now
- endpoint_t defined as u32_t not int
Cleaned up system call library.
Added new alert() trap to replace notify() --- current notify will be removed
and alert() will be called notify() later.
