update systemd service files for new daqd architecture

See merge request cds/advligorts!8

We now have a single daqd service, and separate services for all the
new front end transport components ({zmq,omx,dix}_{xmit,recv},
local_dc, etc.).

The assumption for all the transport services is that the
/etc/advligorts/env file exists and defines environment variables
specifying the command line arguments for each service, e.g.:

ZMQ_XMIT_ARGS=-e eth0 -s x1tst

The daqd service expects configuration at /etc/advligorts/daqdrc.

missed python2to3

See merge request cds/advligorts!6

these are not executables

Update zmq_recv to no longer use IX.  Move it to the zmq_stream dir.

See merge request cds/advligorts!4

Moved a bit of old zmq code to an 'attic' directory in the zmq area.

Ripped out the dolphin bits from zmq_recv_ix_xmit_delay.cc and renamed
it zmq_stream/zmq_recv.cc.

Moved ix_stream/recvr_utils.hh to zmq_stream as it was some debug code
for zmq_recv_ix_xmit.

Change FindDolphin.cmake to look for libs in /opt/DIS/lib as well as lib64

ix_fb_rcv -> ix_recv
zmq_rcv_ix_xmit_delay -> zmq_recv
mx2ix -> omx_recv
ix_xmit - added as placeholder
local_dc - added as placeholder
mx_fe -> omx_xmit
zmq_fe -> zmq_xmit

No longer builder mx_stream.

"2to3 -w .", and changes to shebang lines

The following are now included in the install in a make install:

ix_fb_rcv
zmq_rcv_ix_xmit_delay
mx_fe
zmq_fe

Updated the FindEPICSBase.cmake to make full targets for ca, cas, Com, gdd.

remove build files

See merge request cds/advligorts!1

These files appear to be generated during the cmake configure process,
and therefore shouldn't be in the repo.

This brings in:
* Updates to the cmake build to support FrameCPP 2.6+
* Various startup scripts for Debian8 & Gentoo 3.0
* Daqd files updated to match branch 3.5
* Moved over the ix/zmq/mx stream work from 3.5
* The split of daq_core.h into daq_core.h & daq_core_defs.h to
centralize declarations.

Mindor cleanup in controllerIop.c and moduleLoadIop.c.

  - Removed Duotone info, as not available to Cymac
  - Changed DAC error flag to not produce error if DAC FIFO empty (Normal for Cymac)

kernel object code.

Added a common controllerko.h for kernel module controllers.

Removed ezca.h from skeleton.st.
Update to GDSTP MEDM screen generation code.

Add in changes from master onto rcgtest

Updated rcgversion to 4.0 in header file.
Changed mx_stream Makefile from BSD to DEFAULT Linux.

Added printk capability back into moduleLoadCommon and moduleLoadIop.
