Added C/CXX warning messages similar to MRAA (w/ -Werror).
* Added syslog warning for missing switch cases
* Cleaned up uint vs int usage
* Fixed redifinition errors for C structs
* Added virtual destructors for base classes
* Removed redundant CMAKE_CXX_FLAGS from COMPILE_FLAGS for all three
wrapper languages. The CMAKE_CXX_FLAGS were showing up twice in
the compile commands for the wrappers.
* Added CMake WERROR option to enable/disable warnings as errors for
all targets.
* Disable a handful of compiler warnings for the wrapper cxx files,
this minimizes the number of warnings from auto-generated code).
