hurd: Fix race between calling RPC and handling a signal
* sysdeps/mach/hurd/i386/intr-msg.h (INTR_MSG_TRAP): Make _hurd_intr_rpc_msg_about_to global point to start of controlled assembly snippet. Make it check canceled flag. * hurd/hurdsig.c (_hurdsig_abort_rpcs): Only mutate thread if it passed the _hurd_intr_rpc_msg_about_to point. * hurd/intr-msg.c (_hurd_intr_rpc_mach_msg): Remove comment on mutation issue, remove cancel flag check.
