Add address_to_bytes API.

This will copy an address's "byte format" into a buffer.  The original
intended design is for export_pdu functionality, which tries to do
this "manually" for many address types (and creates undesired dependencies)

The default functionality if a "byte format function" isn't provided
(currently the case for all address types) is a memcpy of the address
data.  Providing "address to byte" functions to aid export PDU
functionality will be provided later.
