Thinking about it again - this actually is a good question. It would be
neat if you could add functionality to your plugins without having to
modify the base Bro installation (which is what you basically do when you
move things to /bro/src and include them into the compile process there -
which certainly is a theoretical possibility).
But - it would be nicer if that was not necessary. So I think my first
idea would be to just put the shared sources into a directory that is
accessible by all your plugins, and compile it together with a plugin (in
separate namespaces so that it does not conflict afterwards).
This should be fine assuming that your shared functionality is not ultra

Yes, your plugins will reside inside the Bro installation in the end.
However you probably should keep your sourecode separate from the main Bro
sourcecode - that's all what I meant :).
