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.
