* cygthread.cc (cygthread::terminate_thread): Wait briefly for notification

event in the event that the thread was actually in the process of exiting.
* pipe.cc (fhandler_pipe::dup): read_state is not supposed to be inheritable.
Fix that.
* path.cc (path_conv::check): Set symlen = 0 to avoid a compiler warning.
* devices.h (devices::parsedisk): Declare new function.
* devices.in (devices::parsedisk): Define new function.
* dtable.cc (dtable::init_std_file_from_handle): Use device numbers rather than
name.
* fhandler_proc.cc (format_proc_partitions): Use parsedisk to generate disk
names from numeric codes.  (This was broken on two of my systems previously and
is still broken now)
