To support runtime policy management, add support for reloading
policy from /data/system. This can be triggered by setting the
selinux.loadpolicy property to 1, whether from init.rc after
mounting /data or from the system_server (e.g. upon invocation of
a new device admin API for provisioning policy). ueventd and
installd are restarted upon policy reloads to pick up the new
policy configurations relevant to their operation.

The qemu-props program is launched at boot to read a series of
system property assignments from the emulator and apply them.
This is necessary to deal with the dynamic nature of the emulated
platform (e.g. the screen density which depends on the skin and
cannot be hard-coded in the platform image).
This patch ensures that qemu-props is started before any other
service that may read one of these properties (e.g. surface flinger).
This is done by encapsulating the program into a 'core' service.
Core services are all stared before regular ones.
Before the patch, qemu-props was started manually inside a script
that is called from a late emulator-specific boot service
(goldfish-setup).
The problem was that sometimes qemu-props was run too late.
This resulted in random flakiness, especially when running
on a low-end host machine.
Fix for bug 2161189 (and probably a few others)

The adb gadget driver used to reset the USB bus when the adbd daemon exited,
and the host side adb relied on this behavior to force it to reconnect
with the new adbd instance after init relaunches it. The new gadget
drivers no longer automatically reset the USB bus when adbd is restarted
which caused adb to hang since it was no longer forced to reconnect with the
device. We attempted to work around this on the host side adb, but that
work around has not been reliable.
This change adds a property trigger on the service.adb.root system property
which will reset the USB bus and restart the adbd daemon when adbd sets
the property to 1. This should be much closer to the previous behavior
and will hopefully fix some problems with automated testing.
