This fixes the crash due to NULL pointer dereference in

Do not try to build the module in case of no INET support but
keep #error calls for now in case we would compile it into the
kernel.
This should fix an issue where the module would fail to enable
IPv6 support from the rc framework, but also other INET and INET6
parts being silently compiled out without giving a warning in the
module case.
While here garbage collect unneeded opt_*.h includes.
opt_ipdn.h is not used anywhere but we need to leave the DUMMYNET
entry in options for conditional inclusion in kernel so keep the
file with the same name.

I have also been told by developers who customize the packet output
path with direct manipulation of the route entry (or the outgoing
interface to be specific). This patch checks for the route mask
explicitly to make sure custom code will not panic.

According to POSIX, these two header files should be able to be included
by themselves, not depending on other headers. The <net/if.h> header
uses struct sockaddr when __BSD_VISIBLE=1, while <netinet/tcp.h> uses
integer datatypes (u_int32_t, u_short, etc).

To run a /31 network, participating hosts MUST drop support
for directed broadcasts, and treat the first and last addresses
on subnet as unicast. The broadcast address for the prefix
should be the link local broadcast address, INADDR_BROADCAST.
- Remove ia_net, ia_netmask, ia_netbroadcast from struct in_ifaddr.
- Remove net.inet.ip.subnetsarelocal, I bet no one need it in 2011.
- fix bug when we were not forwarding to a host which matches classful
net address. For example router having 192.168.x.y/16 network attached,
would not forward traffic to 192.168.*.0, which are legal IPs in
CIDR world.
- For compatibility, leave autoguessing of mask based on class.

When the zone limit was reached not even the missing segment
that would complete the sequence space could be processed
preventing the TCP session forever from making any further
progress.
Solve this deadlock by using a temporary on-stack queue entry
for the missing segment followed by an immediate dequeue again
by delivering the contiguous sequence space to the socket.
Add logging under net.inet.tcp.log_debug for reassembly queue

On raw sockets the IP header should be delivered as it at came in

This brings us in line with all other OS'es that provide raw
