    tcpip: guard tcpip_msg enum/struct member with !CORE_LOCKING
    
    enum tcpip_msg_type and struct tcpip_msg have members which are only
    used when core locking and/or core locking input are disabled. Remove
    these from the union to reduce the size. Remove from enum to prevent
    usage when these are options are disabled
    
    A quick sizeof test with MSVC 2013 showed a 4 byte size reduction for
    struct tcpip_msg (16 bytes -> 12bytes) for the following configuration:
      LWIP_TCPIP_CORE_LOCKING        1
      LWIP_TCPIP_CORE_LOCKING_INPUT  1
      LWIP_TCPIP_TIMEOUT             0
