git-posix_openpt

https://sourceware.org/ml/libc-alpha/2019-12/msg00799.html

Committed for 2.33

Author: Samuel Thibault <samuel.thibault@ens-lyon.org>

    Rearrange bsd_getpt vs bsd_openpt and implement posix_openpt on BSD

    * sysdeps/unix/bsd/getpt.c (__getpt): Add oflag parameter, pass
    it to the _open call and rename to...
    (__bsd_openpt): ... new function.
    [!HAVE_GETPT] (__getpt): Reimplement on top of __bsd_openpt.
    (__posix_openpt): Replace stub with implementation on top of __bsd_openpt.
    (posix_openpt): Remove stub warning.
