Timo Kreuzer 6adc874cbb [SHLWAPI] Use kernelbase 
This replaces implementations that no longer exist in Wine-10.0's shlwapi
Also forward some exports to kernelbase_ros. This is to prevent them from being reimported from shell32, which forwards them here.
It is not exactly what Windows does (which exports the import stubs), but it should be good enough for now.
