CircularDependencyDetector: Avoid deadlock in registerDependencyWait

If a circular dependency was checked and the dependent module was not
yet in the waitMap, the lock was never released.

Print path to the nonvirtual module if oneLevelUp or oneUpAndHide are
detected directly below the applicaiton root.

The user can now also choose to publish messages only to the control
system.

Removed libtine linking workaround from FindDOOCS. Doocs libraries now are themselves linked correctly against tine.

finally managed to cook up a test that is sensitive to the connection errors when using hierarchy modifiers

This closes #29.

Refactored.

Manual check to be used temporarily.

These additions cover the behavior described in #29.

  - Rename, this does not test the intial value propagation
  - Remove debug output

This reverts commit a80ebc2d.

This was the wrong approach, see ChimeraTK/DeviceAccess-DoocsBackend#45

It was agreed to never do this. What strings are for display only and should not be analysed, neither by tests nor by applications.

This helps understanding where an error is coming from, e.g. when multiple devices are used in the same logical name mapped device

This greatly helps debugging real setups, as the messages will usually end up in the server log.
Note: Ideally, a proper logging mechanism should be used instead, but this does not yet exist!

Reading was done only in deeper levels inside the VariableGroups.

See 1af92147. Input accessors are now properly part of the ReadAny group which improves the deterministic behaviour.
