f60aecd8cc 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.

488a727a00 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.

b79a5aa131 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).

a62a3b6e1f Add an EXIT STATUS section to the manual page. Currently, nc(1) 
does not follow sysexits(3), and returns 1 for all error cases.

2d9e1680b9 Merge nc(1) from OpenBSD 4.4. While there, rename our '-O' (no

3302f9bcc3 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.

fe20bac494 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.
