Colin Cross 69d85288cb Rearrange java library outputs
Jack can silently handle using a java library as a static java
library by merging in the java library dex file.  This causes
problems when switching to javac, because dex doesn't support
dex merging with multidex enabled?

Make the output files consistent between java libraries and static
java libraries.  Java libraries will now produce:
classes-pre-proguard.jar: the classes before proguard processing
classes.jar: the final jar file containing classes before dexing
javalib.jar: a jar containing classes.dex

Static java libraries will eventually only produce
classes-pre-proguard.jar and classes.jar.  All inter-library
linking is done with classes.jar, so a java library can be
used as a static java library.

There are too many dependencies outside the build system that
expect javalib.jar to exist for static and host java libraries,
so for now continue to build a javalib.jar that is a copy of
classes.jar.
