commit 2b6e91c2ee4f89c0ee31c83c3a5e5414fd2b3d40

    Report EADDRNOTAVAIL and EADDRINUSE as RESOURCELIMIT
    
    These errors usually mean address exhaustion; reporting them as such
    lets clients adjust their load to try other exits.
    
    Fix for bug 4710; bugfix on 0.1.0.1-rc, which started using
    END_STREAM_REASON_RESOURCELIMIT.
