- respect msgMaxSize in received v3 PDUs (in the weak sense that if

    the serialized response PDU is more than it, we don't send it)

  - removed functions ascii_to_binary, hex_to_binary.  Using these
    functions is really bad, since they will happily overflow buffers.
    The superior alternatives, defined in tools.h, are
    snmp_{decimal, hex}_to_binary.
