Correct ttyslot header declaration conditions (bug 20051).
UNIX98 and XPG4 have ttyslot in <stdlib.h>. glibc, however, has it in
<unistd.h>, for __USE_MISC || (__USE_XOPEN_EXTENDED && !__USE_UNIX98),
but no supported standard has it in <unistd.h>.
This patch adds a properly conditioned declaration to <stdlib.h> (only
enabled for the relevant standards, not for __USE_MISC or __USE_GNU).
The <unistd.h> declaration is restricted to __USE_MISC. Some relevant
XFAILs are removed.
Tested for x86_64 and x86 (testsuite, and that installed stripped
shared libraries are unchanged by the patch).
[BZ #20051]
* posix/unistd.h [__USE_XOPEN_EXTENDED && !__USE_UNIX98]
(ttyslot): Do not declare.
* stdlib/stdlib.h [__USE_XOPEN_EXTENDED && !__USE_XOPEN2K]
(ttyslot): New prototype.
* conform/Makefile (test-xfail-XPG4/unistd.h/conform): Remove
variable.
(test-xfail-UNIX98/stdlib.h/conform): Likewise.
