Add soreceive_dgram(9), an optimized socket receive function for use by
datagram-only protocols, such as UDP. This version removes use of
sblock(), which is not required due to an inability to interlace data
improperly with datagrams, as well as avoiding some of the larger loops
and state management that don't apply on datagram sockets.
This is experimental code, so hook it up only for UDPv4 for testing; if
Out of curiosity could one hook it up for v6 as well or is there code
missing (haven't read the diff yet). There might be people who would want to
test experimental v6 paths as well if possible...
I've hooked up soreceive_dgram() only for UDPv4, but Paul Saab has volunteered
to do UDPv6 testing. Asuming that goes well, I'll hook up UDPv6 sometime soon
also. As far as I know, no code is missing -- in principle, soreceive_dgram()
could also be used for IP raw sockets, Appletalk, IPX, etc, as well.
