[Exp PATCH] Change max protocol count (-sO) when ignoring states

The attached patch (/nmap-exp/kris SVN r4456) changes the max protocol
count (with -sO) when deciding when to ignore certain states. The SVN log:

Change max protocol count when ignoring states. The IPProto Scan wasn't
taken into account when figuring out how many ports/protocols should be
in a given state before ignoring them. For me in most cases, -d caused
every protocol to be listed because most are open|filtered and the -d
set the maximum to a value a lot larger than 255. Now for the same
hosts, it takes -d3 for all of them. This is a value that seems good for
me for most hosts, but I'm going to mail -dev to see if they can do better.
------------------------------------------------------------------------

So if you can test this out, that'd be great. And if you think you have
a better value to put in there, that's even better :)

Thanks,
Kris Katterjohn
