Ethan Atkins 625470cdd5 Make LayeredClassLoaders parallel capable 
The docs for ClassLoader,
https://docs.oracle.com/javase/8/docs/api/java/lang/ClassLoader.html
say that all non-hierarchical custom classloaders should be registered
as parallel capable. The docs also suggest that custom classloaders
should try to only override findClass so I reworked LayerdClassLoader to
only override findClass. I also added locking to the class loading to
make it safe for concurrent loading.

All of the custom classloaders besides LayeredClassLoader either
subclass URLClassLoader or LayeredClassLoader but don't override
loadClass. Because those two classloaders are parallel capable, the
subclasses should be as well. It isn't possible to make classloaders
that are implemented in scala parallel capable because scala 2 doesn't
support jvm static blocks (dotty does support this with an annotation).
To work around this, I re-worked some of the classloaders so that they
are either directly implemented in java or I subclassed a scala
implementation class in java.
