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.
