Current systems do not have BSD terminals, so the fallback code in posix_openpt/getpt does not do anything. Also remove the file system check for /dev/pts. Current systems always have a devpts file system mounted there if /dev/ptmx exists. grantpt is now essentially a no-op. It only verifies that the argument is a ptmx-descriptor. Therefore, this change indirectly addresses bug 24941. Reviewed-by: Adhemerval Zanella <adhemerval.zanella@linaro.org>
