This patch initializes some HAL components greedily so that we can get rid of
lazy initializers within the code. Observers are still lazily initialized
because they can be instanced within content processes but that doesn't always
happen and we don't want to pay the memory price for structures we don't use.
Shutdown is now happening at a fixed time for all HAL components save
WakeLocks. This ensures that we don't destroy an object while still iterating
over it, something that could happen before.
Finally a workaround for a compiler limitation has been removed.
