Optimize generated Android DEX bytecode
* configure.ac (D8): Attempt to locate the bundle where d8 is
installed, detect whether an installation of `r8' is similarly
present, and use this installation in place of d8 if so.
* java/Makefile.in (ANDROID_MIN_SDK, IS_D8_R8): New
substitutions.
(classes.dex): Provide --min-api, --debug or --release and
--pg-conf to d8 or r8.
