ip/udp: Fix IP source address setting for multicast address bound socket

ip/udp: Fix IP source address setting for multicast address bound socket

It is a common practice to bind UDP socket to multicast address to enjoy
kernel level destination multicast address and port filtering. However,
if data are sent on this kind of socket, source address of the IP packet
will be the bound multicast address?!

Two fixes are added to address this bug:

1) Don't set IP source address in udp_output(), if the inpcb's laddr is
multicast address. Instead the IP source address is set to INADDR_ANY,
so ip_output() could pick up a proper IP source address.

2) With 1) in place, it is possible that IP source address is INADDR_ANY
before the ifnet.if_output() using following steps:
- If the IP_MULTICAST_IF socket option is set to iface0
- The iface0's last IP address is unset, before the ip_output()

This condition could easily be reproduced by using test/mcast:
mcast -m 224.2.2.2 -p 3000 -i iface0_ip -D 10
During the 10sec delay, wipe out all IP addresses from iface0

Well, even without 1), raw IP still could generate IP packet using
INADDR_ANY as source address.

Two checks on the source IP address are added to ip_output() before
ifnet.if_output()
- IP source address should not be INADDR_ANY
- IP source address should not be multicast address

And for multicast IP packets, if the IP source address could be
determined, they will not be looped back and forwarded.

This optimization leaves enough space at the beginning of the mbuf, so

sosendudp: Try to optimize out the additional mbuf alloc on output path

This optimization leaves enough space at the beginning of the mbuf, so
later on M_PREPEND() probably will not allocate addition mbuf.

This probably will not benefit any data that will be fragmented, e.g. by
IPv4, so this optimization is only performed when the size of data and
max size of protocol+link headers fit into one mbuf cluster.

This optimization could be turned off by net.inet.udp.sosend_prepend,
which is on by default.

socket: Change sysctl names sosnd -> sosend, no functional changes

pru_send: Allow non-NULL address parameter to be passed

Currently the passed in address is copied into a newly allocated
memory (grr, additional blocking kmalloc), and the PRUS_FREEADDR
will be set

pru_send: Allow non-NULL address parameter to be passed

Currently the passed in address is copied into a newly allocated
memory (grr, additional blocking kmalloc), and the PRUS_FREEADDR
will be set so that protocol thread could know when to free the
address.

Before this change netperf UDP_STREAM (unconnected socket) could
only do ~200Kpps (w/ -m 18), now it could do ~990Kpps (w/ -m 18).
This gives ~500% performance improvement for tiny UDP packet TX.
The improvement is not as good as the connected socket, which is
~600%, mainly because of the additional memory allocation for
the address. We _may_ further optimize out the address allocation.
