    Add debugger utilities to dump variable values
    
    	* src/dbgengine/nmv-debugger-utils.cc,h:
    	(gen_white_spaces, dump_variable_value): New functions.
    	* src/dbgengine/Makefile.am: Add nmv-debugger-utils.cc,h to the build
    	system. It's build into a static library, libdebuggerutils.la.
