We set the system_server classpath in the environment
(like we do with BOOTCLASSPATH). After the zygote forks
the system_server, we dexopt the classpath (if needed)
and then launch the system server with the correct
PathClassLoader. This needed several small / medium
refactorings :
- The logic for connecting to installd is now in a separate
class and belongs in the system_server.
- SystemService / SystemServiceManager have now moved to
classes.jar. They are only used from there, and since they
use Class.forName, we want them to be loaded by the
system_server classloader, and not the bootclassloader.
- BootReceiver now moves to frameworks.jar, because it is
used by ActivityThread and friends.

At startup, we check with PackageManager whether a system service is
available before attempting to load it. A system service is available
if its associated feature (similar to hardware features) is present.
This does not remove unavailable services from the compiled jar.
