In C, signed integer overflow is undefined behavior. Many compilers
optimize away checks like `a + b < a'.
Use safe precondition testing instead.

priority if successful, while the linux syscall returns 0. Also, in
the non-syscall version, we must be sure to set errno to EPERM on failure
since setpriority() can set errno to several possible values.
Note: The version of glibc on my debian system is broken wrt EPERM too.
