This is a usage change - anyone that was previously using
pty for function declarations should now use forkpty
and/or openpty. But it is necessary to get us closer to
providing forkpty replacements on Solaris and HP-UX (not
done in this series, but should be easier now), as well
as a forkpty stup on mingw (which has neither fork() nor
pty's, so the replacement would always fail, but at least
provide avoidance of link failure).
