Message:

introduce device namespaces

• add support for explicit open in libfs (needed by devfs, but also possibly for other filesystems which need to track some stateful information)
• extend libfs to be more generic, make proper adjustments to libc, tmpfs and fat
• various updates to make use of the device namespaces
• code cleanup
