Add tcsetsid(3).
The entire world seems to use the non-standard TIOCSCTTY ioctl to make a TTY a controlling terminal of a session. Even though tcsetsid(3) is also non-standard, I think it's a lot better to use in our own source code, mainly because it's similar to tcsetpgrp(), tcgetpgrp() and tcgetsid().
I stole the idea from QNX. They do it the other way around; their TIOCSCTTY is just a wrapper around tcsetsid(). tcsetsid() then calls into an IPC framework.
