setsockopt wrapper

The libc setsockopt function is set to set various options on a socket. set_socket_option offers a somewhat type-safe wrapper that does not require messing around with *const c_voids.

A proper std::io::Error will be returned on failure.

Example use:

let fd = ...;  // some file descriptor, this will be stdout
set_socket_option(fd, SOL_TCP, TCP_NO_DELAY, 1 as c_int)

Note that the val parameter must be specified correctly; if an option expects an integer, it is advisable to pass in a c_int, not the default of i32.
