This change implements the TLS extension to the x86 ABI.  This allows
threads to have thread-private data which is quickly accessible via a
segment in the GDT, stored in %gs.  The patch implements the relevent
syscalls (setthreadarea), and also manages switching the VCPU's segment
information at thread context-switch time.  Mostly Tom Hughes' work.
