This code essentially converts DAQ data as sent by FE models
to shared memory into new daq_multi_cycle data type in local
shared memory.
Intended use is as DAQ for standalone computers and common interface
for DAQ networking software using ZeroMQ, Dolphin, MX, etc.

Took out entire message CRC checks, which should be fixed and reinserted at some point.

Some fixes to ix_dc_xmit for cycle data size. Now funtional with a ZMQ receiver writing shared memory.

Modified cycle_block_size to align to 8 byte boundary, required upstream for sending data via Dolphin.

When run on gcc 4.4 the zmq_recv process would segfault on the
construction of the zmq receiving object.  This is a rewrite of that
code back to C in hopes that that cleared up an issue specific to gcc 4.4.

At least for testing purposes we need zmq_recv to build on gcc 4.4, so
make it work on the older gcc.  The code still requires c++0x/c++11 but
adds a work around for std::atomic not being available.

   - Send CRC from DC to NDS/FB computers for data verification.
   - Needed 8 byte alignment to multi_cycle data for proper xmission on Dolphin.

Added CRC calculation to dc_xmit, which is compared at dc_fb_rcv.
Moved heartbeat location of ix_multi_stream to ix_rcv_threads.

zmq_recv was not passing the data crc through, fix that.
producer_shmem needed to stop using an old rmIpc structure that no longer
applies.

Added debug output to:
daqd_shmem
fe_stream_test
zmq_multi_stream
zmq_dc_recv/zmq_recv

to show config & data crc values on the output streams.

Had to put back the DIO definitions to allow user space code to build if user app has a DIO card defined.
In user space, code can not actually get to DIO cards in this direct fashion, so will need to be
changed later.

zmq_daq_core.h is not really zmq specific anymore, so take the ZMQ out of
the defines.
