Added new macros:

SYSTRAP(x):             Expands to the code used to call syscall x.
				This is used to simplify other macros.

        SYSCALL_NOERROR(x):     Like SYSCALL except that "x" is a syscall
				that can never fail.

        RSYSCALL_NOERROR(x):    Like RSYSCALL except that "x" is a syscall
				that can never fail.
