GATT: Handle prepare_authorize parameter in WriteValue DBUS API
In GATT Server role, prepare_authorize parameter will be set
when bluez wants authorization permission from the application when
ATT_PREPARE_WRITE_REQUEST PDU receive for the first time in case
of long write.
This is an initial patchset to parse prepare_authorize parameter from
bluez and avoid crash. Subsequent patches will be added to handle
authorization completely.
This patchset should be merged with the following bluez's patchset
in order to match API and avoid crash:
