ttyname_r: Add missing declaration on HP-UX 11.
* lib/unistd.in.h (ttyname_r): Test HAVE_DECL_TTYNAME_R instead of
HAVE_TTYNAME_R.
* m4/ttyname_r.m4 (gl_FUNC_TTYNAME_R): Test whether ttyname_r is
declared. Set HAVE_TTYNAME_R always.
* m4/unistd_h.m4 (gl_UNISTD_H_DEFAULTS): Initialize
HAVE_DECL_TTYNAME_R, not HAVE_TTYNAME_R.
* modules/unistd (Makefile.am): Substitute HAVE_DECL_TTYNAME_R, not
HAVE_TTYNAME_R.
* doc/posix-functions/ttyname_r.texi: Document the HP-UX 11 problem.
