Add PSEUDO_NOERROR similar to that used by NetBSD.
Some ports were setting errno in PSEUDO and some were not. Now errno is set for all in PSEUDO and PSEUDO_NOERROR is provided for the non-errno case (only used by _exit). Needs testing on vax and m88k. XXX - hppa and powerpc still lack a real PSEUDO_NOERROR implementation. Currently PSEUDO_NOERROR and PSEUDO are the same (so builds don't break on those platforms).
