Message:

bs3kit: A bunch of changes to be able to test the effects of a GDT page being read-only or not-present.

• Extended the GDT so we get a whole page to play paging tricks with.
• Added syscall for restoring a context from ring-0 so we can safely get out of bogus test context that aren't in ring-0 (non-standard CS value causing trouble here). Implemented the string print syscall since the restore syscall forced me to sort out pointers.
• Changed most string printers to do more than one char at a time (usually a line) to save context switches (screen priting is done via INT 10h in real mode).
• Test the CS access bit handling during INT XXh.
