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.

Next step is clean up and test.

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.

The daqd_shmem had been overwriting TP data with regular data from the next dcu.
Advance the destination pointer the proper length to not overwrite test points.

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

Also, fix for running without CPU SHUTDOWN.  This is still has unstable timing, but at least
module can be unloaded/reloaded now in this compile option.

A number of structures have common portions, extract the common header fields.

Fixed a spurious copy/paste error in comm_impl.cc.

Moved the zmq_recv from using a max number of dcus to using a max transmission size.

Combined the data/gds structures into one.  Updated the logic to allow
moving data from the fe simulation through to the daqd.  Partial work
on the daqd_shmem system (not complete).

Pulled some logic out of comm.y and placed it in its own files
comm_impl.cc/hh, to aid in debugging/tool introspection.

daqd_shmem is similar to a standiop.  However it reads data from one combined shared memory segment, does not require a timer or adc card.

Updates to the fe_stream_test to put data in the proper places.

Additional test scripts and commands to help manipulate and introspect mbuf memory buffers.
src/drv/mbuf/mbuf_probe
src/zmq_stream/scripts/dump_zmq_core_structs.py

Added a zmq_recv command to receive data from a zmq stream and publish it to a local mbuf.

Adding a new c userspace interface to the mbuf shared memory.

	- Better IOP sync at 64K
	- Addition of memory space for a virtual ADC for IOP to read input from.
