Applied patch, thanks!

rpaulo 2fb2ae3251 Import of TCP ECN algorithm for congestion control. 
Both available for IPv4 and IPv6.
Basic implementation test results are available at
http://netbsd-soc.sourceforge.net/projects/ecn/testresults.html.

Work sponsored by the Google Summer of Code project 2006.
Special thanks to Kentaro Kurahone, Allen Briggs and Matt Thomas for their
help, comments and support during the project.

rpaulo 63b3e9f51c It's not an error if we can't print CARP stats, it just means it's not built 
in.

elad 5d7aa1a613 Make netstat use sysctl when dumping routing tables/stats. 
Heavily based on similar code from Claudio Jeker (at OpenBSD).

While here, fix inet/inet6 sysctl stuff commited previously to
actually work, and some other nits to make netstat more sysctl
friendly.

One step closer to losing setgid kmem on this one...

riz 64cde4117b Use PRIu64 to format uint64_t quantities, instead of %llu, in 
newly-introduced code.

XXX more %llu cleanup is needed throughout netstat code.

he 80ccb5520c As a temporary workaround, apply the fix from PR#20390, thereby 
cooperating with the callout code in working around the race
condition caused by the TCP code's use of the callout facility.

Instead of unconditionally releasing memory in tcp_close() and
SYN_CACHE_PUT(), check whether any of the related callout handlers
are about to be invoked (but have not yet done callout_ack()), and
if so, just mark the associated data structure (tcpcb or syn cache
entry) as "dead", and test for this (and release storage) in the
callout handler functions.

jdolecek 842b4adcdc it's not necessary to limit the service name artificially to 8 characters 
in inet*print() - only first 'width' characters of the 'host.service'
string would be printed anyway, so allow full service name if string would fit

lukem e16c1d5cbc if not -n and the local socket doesn't have INP_ANONPORT set, always try 
to determine the symbolic name of the foreign port.

previously the foreign port would be displayed numerically in this case if
the local & foreign ports were different.  this particular behaviour was
added in rev 1.28 when I added INP_ANONPORT support from FreeBSD, and for
the life of me I can't fathom the rationale for it ;-|
