There was a long-standing issue that pseudo console ownership could not hand over from the process whose ctty is /dev/cons* rather than /dev/pty*. This problem happens when a cygwin app starts non-cygwin app in a pty, then the non-cygwin app starts multiple cygwin apps, and the non-cygwin app ends before the second cygwin apps end. In this case, the stub process of the non-cygwin app hands over the ownership of pcon to one of the second cygwin apps, however, this app does not hand over the ownership of pcon to another second cygwin app. This is due to the fact that the hand-over feature is implemented only in fhandler_pty_slave but not in fhandler_console. With this patch, the second cygwin apps check if their console device is inside a pseudo console, and if so, it tries to hand over the ownership of the pseudo console to anther process that is attached to the same pseudo console.
