This adds the '-prop <name>=<value>' option which is used to set
boot-time system properties from the command line. This is done
by implementing a new 'boot-properties' qemud service in the emulator.
This is to be used by the 'qemu-props' helper program that will be
invoked by /system/etc/init.goldfish.rc to read a list of system
properties from the emulator and set them in the emulated system
during boot.
