In the long run, we're probably going to want to coalesce multiple
getPrimaryService() calls that happen in the same message loop turn, into a
single request that takes a group of UUIDs. That'll reduce the number of
renderer<->browser IPCs and help the browser pick the right GATT procedure to
discover those services. Similarly for the other get*() calls.

You don't need to make the IPC support that right now.

Ack.
