[PATCHv4 01/11] android: Create HAL API header skeleton

[Andrei Emeltchenko <Andrei.Emeltchenko.news@gmail.com>]

From: Andrei Emeltchenko <andrei.emeltchenko@intel.com>

Header describes the protocol between Android HAL threads and BlueZ
daemon. The header is added to host build and not to Android since
it is smart enough to include it automatically.
