0772266e63 MFV r249496,249498. The most visible change is that we no longer shuts 
down the connection when stdin closes, by default.  This matches Hobbit's
original netcat and GNU netcat.

Old behavior can be restored with the new -N flag.

aaf04b7cb6 Switch from setfib(2) moving the process to a different FIB to setsockopt(2) 
with SO_SETFIB to only tag the socket with the right FIB.

That way either setfib(1) or nc -V can be used depending on what wants to be
achieved.  This also allows nc to be used for simple regression testing of
either feature.

bc6940585f Use "printf" instead of "echo -n" in an example because it 
should be more compatible for most shells that are out there.

I contacted Philip Guenther at OpenBSD about this PR and he
corrected the issue in their tree pretty fast.

f15e71c26a Fix .Dd value -- our mdoc macros don't know how to parse the $Mdocdate$ 
tag, so the file was being treated as having no date (i.e., the current
date was being inserted).

04def62430 Finish the import of nc(1) from OpenBSD. This includes: 
- Bring IPsec support from the ports collection [1].
	- Bring -o ("once only") option from the ports
	  collection [2].
	- Adopt the Makefile framework into
	  usr.bin/nc/Makefile.
	- Add a knob to control whether to build nc(1),
	  NO_NETCAT.
	- Bump __FreeBSD_version so ports collection can
	  detect this change.

Original patchset are contributed to the ports collection by:
[1] nectar, [2] joerg.

Note: WARNS?=6 patchset spined off in this commit, in order not
to take too many files off the vendor branch.

8c384020b3 Import a (stripped) snapshot of OpenBSD's nc(1) an excellent 
reimplementation of the famous tool that can do arbitrary TCP
and UDP connections and listens.

This gaves sysadm the same tool the crackers have, so that
they may learn what the network is about and protect it better.
For developers, this is an invaluable debugging tool, and a
good build block of scripts.
