Initial import of udpcast-20060619, requested in PR 34171:

UDPcast is a file transfer tool that can send data simultaneously
to many destinations on a LAN. This can for instance be used to
install entire classrooms of PC's at once. The advantage of UDPcast
over using other methods (nfs, ftp, whatever) is that UDPcast uses
Ethernet's multicast abilities: it won't take longer to install 15
machines than it would to install just 2.
