oxenstored: Enforce a maximum message size of 4096 bytes

The maximum size of a message is part of the protocol spec in
  xen/include/public/io/xs_wire.h

Before this patch a client which sends an overly large message can
cause a buffer read overrun.

Note if a badly-behaved client sends a very large message
then it will be difficult for them to make their connection
work again-- they will probably need to reboot.
