[hurd, commited] Rearrange bsd_getpt vs bsd_openpt and implement posix_openpt on BSD

[hurd, commited] Rearrange bsd_getpt vs bsd_openpt and implement posix_openpt on BSD

[Samuel Thibault]

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