9ad96316d8 Cleanup the ECN configuration handling and provide an SCTP socket 
option for controlling ECN on future associations and get the
status on current associations.
A simialar pattern will be used for controlling SCTP extensions in
upcoming commits.

529b98b943 * Provide information in error causes in ASCII instead of 
proprietary binary format.
* Add support for a diagnostic information error cause.
  The code is sysctlable and the default is 0, which
  means it is not sent.

This is joint work with rrs@.

10b033d327 For now limit printf(9) %x of the 64bit pkthdr.csum_flags field to 32bits. 
The upper 32bits are not occupied for now.

afd48faca0 Remove the large part of struct ipsecstat. Only few fields of this 
structure is used, but they already have equal fields in the struct
newipsecstat, that was introduced with FAST_IPSEC and then was merged
together with old ipsecstat structure.

This fixes kernel stack overflow on some architectures after migration
ipsecstat to PCPU counters.

fea857f2a8 Do not reduce ip_len by size of IP header in the ip_input() 
before passing a packet to protocol input routines.
  For several protocols this mean that now protocol needs to
do subtraction itself, and for another half this means that
we do not need to add header length back to the packet.

  Make ip_stripoptions() to adjust ip_len, since now we enter
this function with a packet header whose ip_len does represent
length of entire packet, not payload only.

5cc3ac5902 Switch the entire IPv4 stack to keep the IP packet header 
in network byte order. Any host byte order processing is
done in local variables and host byte order values are
never[1] written to a packet.

  After this change a packet processed by the stack isn't
modified at all[2] except for TTL.

  After this change a network stack hacker doesn't need to
scratch his head trying to figure out what is the byte order
at the given place in the stack.

[1] One exception still remains. The raw sockets convert host
byte order before pass a packet to an application. Probably
this would remain for ages for compatibility.

[2] The ip_input() still subtructs header len from ip->ip_len,
but this is planned to be fixed soon.
