4ffe8ffc0f Put Windows timer functions into PBD namespace in preparation for moving them to libpbd
Add functions for get/set the Multimedia timer resolution, although we are
really only interested in the minimum, this will facilitate testing

Put timer utility functions inside nested namespaces as they are platform
specific
