vt, ssh: don't send interrupts on window resize When resizing windows, vt would signal ssh by updating the window size and sending an interrupt. Ssh reacted by forwarding both the winch and an interrupt. This change adds a WINCH generation counter so that ssh can differentiate between resizes and interrupts. If an interrupt comes in, and the WINCH generation changes, then the interrupt is taken as signalling a WINCH.
