It is possible to set values too quickly into the
referenceTestApplication sender process variables leading to buffer
overflows and loss of information in the receive variablesr queue.

The test was failed intermittently for this reason, A sleep has been
used to slow down the producer as a woe	, but a proper fix would involve
the referenceTestApplication doing its own rate limiting on buffer
overflow situations.

- Revised logic for checkSourceConsistency
- invoke set_ro_access if all ifff sources are readonly.

All IFFF sources must be consistently readable/writable. A logic error
is thrown if this is not the case.

Added code to support zmq sending in cretaeDoocsIfff function.

* compiles but untested
* existing tests for app->CS still passing.

- Shows up in Doocs
- Test does not check functionality yet, just that it's there

  - Clean up serverTestDataMatching
  - Fix missing include in test

  - Fix default setting for imported locations (solves #39)
  - Test for imported scalar properties

- was confusing milliseconds and microseconds for the archiver
- was not setting the global time stamp

Since Doocs 20.1 this is thrown if the name of the property exceeds 64
characters

This is a new requirement from ApplicationCore.
