Bluetooth MAP (Message Access Profile) Upstream Changes (3/3)

Incorporates updates to the Bluetooth MAP profile from Code Aurora's
Android Enablement Project since we initially pulled in from their
gingerbread to CM7 last year. This patch addresses bugs with the
current MAP profile, adds a UI request for message access approval
when pairing, and adds additional error checking and logging.
Confirmed to fix date and "Download" function of Ford SYNC Gen1.
Pulled in from the codeaurora jb branch.
