Add versions of stpcpy(3), stpncpy(3), strnlen(3), all from FreeBSD.
These are defined in the latest POSIX Also make related updates to documentation, mostly from FreeBSD, though I cleaned a few other things up along the way. Bump shlib_version. We are still missing strcoll_l, strerror_l, strsignal, strxfrm_l to be POSIX conformant.
