Log Message:
socket: report receive buffer overflows

Add soroverflow() which increments the overflow counter, sets so_error
to ENOBUFS and wakes the receive socket up.
Replace all code that manually increments this counter with soroverflow().
Add soroverflow() to raw_input().

This allows userland to detect route(4) overflows so it can re-sync
with the current state.
