Subject: build the error message in strerror_r.c directly, avoiding one copy
 there. handle a few subtle details caught by the regression tests: correct
 termination, non copying if buffer length == 0, errno setting. let all former
 users of __strerror go through strerror_r.

Work by Todd Miller and I. Okay millert@.
