X-Git-Tag: android-x86-4.4-r3~8264
X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=b5c339804950551cba3bc07051dc339ad0a1db2c;p=android-x86%2Fexternal-bluetooth-bluez.git

core: Add btd_service to represent device services

Add a new object to centralize all data corresponding to a service
provided by a remote device, coupling a pair of btd_profile and
btd_device pointers.
