Introduce new V4 format addrman

Browse Source 
92617b7a75 effectively changed the
on-disk format in an incompatible way: old deserializers cannot
deal with multiple entries for the same IP.

Introduce a V4_MULTIPORT format, and increment the compatibility base,
so that old versions correctly recognize it as an incompatible future
version.
