Noel Eck 6725559669 JAVA: Remove library source compile from JAVA packages 
Previously the JAVA packages re-compile UPM library source files.  This
was a work-around for compiling JAVA-specific functionality from the UPM
source into the SWIG'ed JAVA pacakges.

This commit removes the source from the JAVA SWIG compile and provides
an example on how to add the JAVA-specific code with a swig extend call.

    * Added _upm.i file for %import (not %include)
    * Added macros to _upm.i; 1 which performs the loadLibrary, and one
      which adds the java installISR runnable.
    * Updated the src/CMakeLists.txt file to NOT build library src into
      pacakges.
    * Updated the a110x library with examples on how to use the macros.

# Selectively disable certain CXX warnings for SWIG wrappers
# SWIG wrappers emit -Wdelete-non-virtual-dtor and -Wunused-function warnings
# Unfortunaly this quick fix for issue #518, adds a .c file to the
# java swig wrapper which then failes on CXX compiler warnings. For
# now, turn off warnings as errors for all the swig wrappers.
