Network stack refactor This introduces CNetAddr and CService, respectively wrapping an (IPv6) IP address and an IP+port combination. This functionality used to be part of CAddress, which also contains network flags and connection attempt information. These extra fields are however not always necessary. These classes, along with logic for creating connections and doing name lookups, are moved to netbase.{h,cpp}, which does not depend on headers.h. Furthermore, CNetAddr is mostly IPv6-ready, though IPv6 functionality is not yet enabled for the application itself.

Cleanup code using forward declarations. Use misc methods of avoiding unnecesary header includes. Replace int typedefs with int##_t from stdint.h. Replace PRI64[xdu] with PRI[xdu]64 from inttypes.h. Normalize QT_VERSION ifs where possible. Resolve some indirect dependencies as direct ones. Remove extern declarations from .cpp files.

Remove I2P support from netbase I2P apparently needs 256 bits to store a fully routable address. Garlicat requires a centralized lookup service to map the 80-bit addresses to fully routable ones (as far as I understood), so that's not really usable in our situation. To support I2P routing and peer exchange for it, another solution is needed. This will most likely imply a network protocol change, and extension of the 'addr' message.
