[Bro-Dev] Geo Location Plugin

Thanks all. After moving declarations around, nm shows all my expected
symbols to be defined. I'm now receiving "internal error in
/usr/local/bro/share/bro/base/init-bare.bro, line 1: internal type
geo_location missing". It seems this error is being caused by the
check on the return value of lookup_ID() done within the
internal_type() function in Var.cc. From what I can tell, I don't have
geo_location = internal_type("geo_location")->AsRecordType();
in the right location. This line is from the init_net_var() function
from NetVar.cc, which gets called by main.cc. I thought it might be a
clash in name/module spaces and tried using the init-plugin script
with some unique values, but I still receive the same error. I'm not
sure if it matters but I when I run "bro -NNb" I can see my inactive
dynamic plugin, so I know Bro is aware of it. I currently have
everything sitting in a single .bif file. Would it be useful to post
