Switch to using POSIX pseudoterminals.

Browse Source 
Previously, we were using SysV pseudo-terminals on Solaris and BSD
pseudo-terminals on other Unix platforms. BSD pseudo-terminals have
been deprecated on Linux and are no longer available in some kernel
configurations.

The POSIX API is basically the same as the SysV API, apart from using
`posix_openpt` instead of `open` with `/dev/ptmx`.

Closes interlisp/medley#121.
