Fix build warnings in Windows.

1. warning: passing argument 4 of 'event_set' from incompatible pointer type [-Wincompatible-pointer-types]
   --> libevent expects callbacks to use evutil_socket_t for fd instead of int. Current code works fine in *nix because it's just int but not in Windows because it's defined as intptr_t.
2. warning: passing argument 4 of 'getsockopt' from incompatible pointer type [-Wincompatible-pointer-types]
   --> Apply casting for Windows' getsockopt call
3. warning: cast from pointer to integer of different size [-Wpointer-to-int-cast]
   --> Replace %lx with more portable %p. long is just 32-bit in 64-bit Windows.
