Reorganize java and android source.

platform/java and platform/android are reorganized:

   platform/java
      The new JNI Java classes, mupdf_native.{c,h}, Makefile and Makejar.

   platform/java/example
      The example desktop viewer classes.

   platform/android/viewer
      The original demo viewer.
      ndk-build is used to build libmupdf_java.so,
      making reference to mupdf_native.{c,h} in platform/java.
