                Remove exception threads.  Replace with support for activations.
                * thread.h (THREAD_SLOTS): Bump to 3.
                (struct thread): Add field exception_page.  Remove fields
                have_exception and exception.
                (thread_exregs): Take additional arguments exception_page and
                exception_page_out.  Update users.
                (thread_raise_exception): New declaration.
                * thread.c (THREAD_VERSION): Define.
                (thread_init): Remove code related to the exception thread.
                (thread_commission): Likewise.
                (thread_decommission): Likewise.
                (thread_exregs): Likewise.  Take additional arguments
                EXCEPTION_PAGE and EXCEPTION_PAGE_OUT.  If CONTROL contains
                HURD_EXREGS_GET_REGS and EXCEPTION_PAGE_OUT is not NULL, return 
a
                capability to THREAD's exception page in *EXCEPTION_PAGE_OUT.  
If
                CONTROL contains HURD_EXREGS_SET_EXCEPTION_PAGE, then set 
THREAD's
                exception page to EXCEPTION_PAGE.
                (thread_raise_exception): New function.
                * server.c (server_loop): Remove code related to handling the
                exception thread.  Call thread_raise_exception to propagate
                exception.  Reimplement the exception_collect method.  Update
                implementation of the thread_exregs method to support the new
                argument passing scheme.  Add support for setting and retrieving
                the exception page.
                (REPLYW): Only clear MSG here.
                * rm.h (exception_collect): Take an additional argument, the
                principal.
                * object.h (object_type): New function.
