changes to accommodate nacl:
* change ldt0setup to set GS itself; nacl won't let us do it.
* change breakpoint to INT $3 so 8l can translate to HLT for nacl.
* panic if closure is needed on nacl.
* do not try to access symbol table on nacl.
* mmap in 64kB chunks.
nacl support:
* system calls, threading, locks.
