Adjust some MDS related constants.
MDS_DIRECT_BUF_MAXSIZE defines the max size sending an unencoded message. This
is changed to reflect the new fragmentation limit.
MDTM_NORMAL_MSG_FRAG_SIZE defines the fragmentation limit supported by old MDS
cores. Since the receive buffer was 8000 bytes, we change it to that.
PAYLOAD_BUF_SIZE is a core constant that defines buffer size of each usrbuf.
By increasing this value to 8000, less processing overhead for chaining buffers
is needed. In the normal case all messages will fit into one usrbuf.
