* ipv4.c: IGMPv3 support (IP_ADD_SOURCE_MEMBERSHIP) for Win32 

 * udp.c: restored the old syntax udp:server_addr@destination_addr
 * libvlc.h: updated 'vlc --help'

 To do an IGMPv3 query under Windows XP do:
 vlc udp:<source_addr>@<multicast_addr>
 Note: under previous versions of Windows, it will fail to join the group.
