(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
