It might often be useful to write output to cout when dumping a trie,
but sometimes it might be useful to dump ot to something else like a
string stream instead.

These files aren't a collection of miscellaneous stuff, they're the
definition of the Logger interface, and a few utility macros for
calling into that interface (panic, warn, etc.).

Dumping the structure of the tries being constructed was useful for
debugging when the trie data structure was being developed, but the
output can't be automatically verified easily, and what's considered
correct depends on the specific implementation of the trie itself.
To make some of the earlier tests more meaningful, additional lookups
were added which verified that the correct values were returned when
the nodes of the trie were in particular arrangements.

trie.hh uses assert, but it wasn't explicitly including cassert.

This change adds a trie data structure which stores an arbitrary pointer type
based on an address and a number of relevant bits. Then lookups can be done
against the trie where the tree is traversed and the first legitimate match
found is returned.
