Make the SO_TIMESTAMP sockopt work. When set, this allows the user to
get a timestamp of when the datagram was accepted (by udp(4), for
example) rather than having to take a timestamp with gettimeofday(2)
when recv(2) returns - possibly several hundreds of microseconds later.
May be of use to those interested in precision network timing schemes
or QoS for media applications. Tested on alpha, amd64, i386 and sparc64.
