Re: [PATCH BlueZ 1/2] adapter: add a btd_adapter_get_default_address() call

Add a new btd_* call to get the default adapter address as a string.

This is meant to be used, for instance, by _external_ plugins which want
to know the default adapter address for some reason (e.g. to send it to
a device for some custom pairing scheme like in the case of Playstation
peripherals).

External plugins can only use symbols marked as "global" in
src/bluetooth.ver, this patch avoids making global these symbols:

  adapter_get_address
  bt_malloc
  ba2str
