Provide new keyword "fobid" to define those forbidden probe, also
permit mistake in declaration
Example:
$ cat /tmp/1.stp
global i
forbid kernel.function("sys_w*"), kernel.function("no_such")
probe kernel.function("sys_write") {
println("wrong")
exit()
}
probe kernel.function("sys_read") {
println("read")
i++
if (i==10)
exit()
}
$ sudo ./stap -v /tmp/1.stp
