ntop: update to 4.1.0

[ryandesign (Ryan Carsten Schmidt)]

ntop should be updated to the latest version, currently 4.1.0. This should resolve a few of the outstanding ntop tickets including #28457. I've been working on this update but don't use ntop so I don't know if it works properly. I'll attach my patch later.

Here's my patch finally. It does many things:

• update port to 4.1.0
• rewrite master_sites to avoid redirects
• add automake, autoconf, libtool build dependencies so we're not using possibly obsolete OS versions
• add python27 dependency and add env vars to use it
• remove unnecessary configure cflags and args
• rewrite startupitem to use startupitem.executable and no longer need ntop.sh wrapper
• install sample config file and databases; don't register them to the port so they're not clobbered at port upgrades
• enable universal variant
• patch autogen.sh to not require wget
• patch autogen.sh to look for libtool.m4 in ${prefix} instead of /usr/local
• patch configure to not look in /usr/local or hardcoded /opt/local
• patch configure to find python
• patch configure to fix syntax errors in removal of arch flags from python config output
• patch configure to no longer use obsolete 2002-era Mac OS X versions of ltconfig and ltmain.sh; this fixes the port so it's UsingTheRightCompiler which addresses comment:ticket:28457:6
• patch configure to use MacPorts libtool
• remove patch-external-geoip.diff; I don't know what to do with that right now

I don't use ntop so I don't know if it still works correctly.

The universal variant almost works; the reason why it was originally disabled no longer applies, but though the ntop program and its dylibs end up being universal, none of the plugins in ${prefix}/lib/ntop/plugins/ do. So that still needs to be fixed.

Committed in r94641. Did not re-enable universal variant since I could not immediately figure out how to fix its problems.
