.Dx (DragonFly) macro-ized man pages

Here is a big batch of man pages updated to include .Dx where we mean 
DragonFly, and .Fx where we mean FreeBSD.  The patch to add the .Dx macro is 
part of this diff.  One file (gnu/usr.bin/groff/tmac/groff_mdoc.man) will 
need to be added to the repo.

Below are some random notes I thought might be significant; however, after 
going through all those man pages, I don't know that my brain works well 
enough for me to trust its judgment. ;)

I tried to keep my changes as accurate and unintrusive as possible; thus there 
are references to, say, "DragonFly/FreeBSD" on pages talking about whether or 
not interesting NIS features work with certain server OSes.

I'm sure this isn't complete yet -- my major criterion was looking for .Fx 
macros, and I did run across a few naughty man pages that used 'FreeBSD' when 
they meant .Fx.  Haven't looked exhaustively for those yet.
	Hmm... I think we definitely should not do a mechanical s/Fx/Dx/
	substitution.  For example, historically, the Dummynet traffic
	shaper first appeared in FreeBSD version X.X, and not DragonFly.
	It is not fair to just take the credit and say it first appeared
	in DragonFly, which is clearly untrue. :-)
	This patch will need to be broken down into bits, I will commit
	it piece by piece, and the other parts I will do more look-see.
	Is this OK with you, and others?
