Initial conversion of uint32_t addr to tor_addr_t addr in connection_t and related types. Most of the Tor wire formats using these new types are in, but the code to generate and use it is not. This is a big patch. Let me know what it breaks for you.

Refactor tor_addr_from_string: it didnt need most of parse_addr_mask_port_range, and its dependence on that latter function made it less flexible.
svn:r16255
Tor_addr_compare did a semantic comparison, such that ::1.2.3.4 and 1.2.3.4 were "equal". we sometimes need an exact comparison. Add a feature to do that.
