* Removed no longer needed disk device related syscalls

(_kern_{supports,validate}_*(), etc.).
* Adjusted the prototypes of the disk device modification syscalls.
  Commented out their implementations for the time -- they'll mostly
  have to be rewritten completely.
* Implemented the userland disk device jobs.
