* pinfo.cc (_pinfo::set_ctty): Revert 2012-02-07 change to skip function if tty 

in question == our ctty.
* syscalls.cc (setsid): Avoid two function calls.
* dtable.cc (dtable::dup_worker): Remove debugging.
* init.cc (search_for): Calculate for every new process rather than using
shared value.
(threadfunc_ix): Fill in for ever new process rather than sing shared value.
