gps: Add loc_eng_set_privacy function to enable/disable GPS privacy lock.

Privacy lock is enabled on loc_eng_init, disabled on loc_eng_cleanup,
mimicking the behavior of TW.  Requires system property
ro.gps.set_privacy=1 to enable/disable privacy lock.

The privacy lock state is non-volatile, and control of the lock is needed
to ensure that the GPS works and is responsive to requests.  Otherwise the
GPS may silently cease to work depending on its last state in TW.

jf: Enable tunnel audio

 * Out with LPA, tunnel mode is the new hotness.
 * Tunnel mode sends compressed audio streams directly to the Hexagon
   where it's decoded and processed, rather than decoding in userspace
   and sending huge buffers of PCM data.
