This files aim to add a simple event support to the kernel.

These are the kernel and user files (the kernel/Makefile must be modified to include evnt.o in the objects):

• entry.S : definition of sys_my_evnt entry in the sys_call_table
• unistd.h : definition of the systen call __NR_my_evnt
• evnt.h : new file with the definition of the struct evnt_struct
• evnt.c : new file with the implementation of sys_my_evnt(int flag, int id) and the other do_evnt_XXX functions
• event.h : user .h file
• test1.c : user program that creates/removes an event
• test2.c : user program that waits on an event
• test3.c : user program that signal on an event
• test4.c : user program that prints the event wait_queue lists (using printk)
