RootCanal: Reuse device addresses

The address is directly derived from the device identifier.
This change modifies TestModel to reuse identifiers from
disconnected devices.

The option is enabled by default and disabled by passing the
parameter --disable_address_reuse

Test: m root-canal && manual check
