    package.bbclass: Add SHLIB detection support for mingw targets
    
    Add support to detect dll files as shared objects as well as process
    Windows .dll and .exe files to determine the runtime libraries
    dependencies.
    
    This implementation is sufficient to detect and map runtime library
    dependencies between packages. And does not implement any version naming
    conventions that might apply for .dll files (e.g. lib*-x.dll).
