Updating the daqd and transports to work with larger buffers.
- Updated constants to use a maximum of 140MB for a daq_multi_cycle_data_t type
- Updated min/max daq shared mem buffer sizes
- Use the min/max constants in applications
- Updated local_dc, cps_xmit/recv, fe_simulated_streams
- Set a default value of 100MB so that it can integrate into existing workflows w/o breaking them
- The default can be increased later or larger sizes can be specified.
