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
