			Currently we define a QEMU-internal errno TARGET_QEMU_ESIGRETURN only on the MIPS and PPC targets; move this to errno_defs.h so it is available for all architectures, and renumber it to 513. We pick 513 because this is safe from future use as a system call return value: Linux uses it as ERESTART_NOINTR internally and never allows that errno to escape to userspace.
