Refactored lcd's into lcd and lcd_thread. Still need to test/update
tests.

Updated code. Removed gdt/tss/idt for now. Added doc directory
and some initial doc.

Was getting bad load/store msr addresses for vm exits.
Properly detected by the lcd_arch_check code.

In struct lcd_arch, the msr_autoload fields were not
word aligned in some instances (see requirement
in Intel SDM V3 26.2.1.2). Even with compiler align
attributes, if we use kmalloc, proper alignment is
not guaranteed - we can allocate a struct lcd_arch
on the wrong byte and it throws off the alignment
of the entire struct.

kmem cache allows specifying alignment. Appears to be
working correctly.

basic error checking, so non syntax errors can be caught, and execution can end after parsing, without crashing

Just need to handle failures gracefully.

IPC in place. Most api calls in place, finishing implementation of
api kill / tear down of lcds.
