* Move ptmx into pty(4).ed2009-09-061-0/+18
| | | | | | | | Now that pty(4) is a loadable kernel module, I'd better move /dev/ptmx in there as well. This means that pty(4) now provides almost all pseudo-terminal compatibility code. This means it's very easy to test whether applications use the proper library interfaces when allocating pseudo-terminals (namely posix_openpt and openpty).
* Allow pty(4) to be loaded as a kld.ed2009-08-231-0/+141
Unfortunately, the wrappers that are present in pts(4) don't have the mechanics to allow pty(4) to be unloaded safely, so I'm forcing this kld to return EBUSY. This also means we have to enable some extra code in pts(4) unconditionally. Proposed by: rwatson
