* cygthread.cc (cygthread::detach): Make error message a little more detailed.

* fhandler.cc (fhandler_base::raw_read): Ditto for debug message.
* dcrt0.cc (do_exit): Add some more synchronization tests.
* fhandler_fifo.cc (fhandler_fifo::dup): Don't duplicate a nonexistent handle.
Use derived return value rather than always retuning 0.
* fhandler_netdrive.cc (fhandler_netdrive::exists): Wnet -> WNet.
* winsup.h (exit_states): Add a couple of new exit states.
