Ed Schouten 1a643b0f02 Allow the user to suppress the rate-limited pty(4) warning.
The pty(4) driver raises up to warnings when an old BSD-style PTY is
created. The reason why I added this warning, was to make it easier to
spot applications that allocate BSD-style PTY's, while they should just
use openpty() or posix_openpt().

Add a sysctl, which allows you to override the number of remaining
messages, making it possible to suppress the warnings.
