Support any type in bif const declaration.

Browse source 
Revamp of const delcaration in bifs:
* Can only declare are const in the bif, but we cannot assign a value
  or attribute to it. One has to do this in a policy file (bro.init)
* Type specification in bif is now mandatory
* Support any type in bifs (previously only bools were supported).

This will also help with automatic documentation generation, since all
const are now defined in the policy layer and thus can be documented
from there. The bif just gives the C++ layer easy access.
