Just use enableDebugDataLoss() to enable debug output.

was already removed for the ScalarAccessor and is tested at least there

ScalarPollInput and ArrayPollInput: Removed doReadTransfer, which does not make sense in the interface

added missing implementations of writeDestructively() - the inherited ones from the DeviceAccess classes are not doing the right thing...

bidirectional variables: pass on version numbers in modules from the last blocking read on to any write operations, to resolve conflicts of concurrent variable updates properly

Added preliminary support for bidirectional variables. There are still some known issues, e.g. concurrent updates can still lead to race conditions. This will be addressed soon.

Unfortunatly this currently breaks the ServerHistory module, as it relies on slashes in accessor names. The MicroDAQ module had the same issue but has already been fixed. This fix can be adopted to the ServerHistory module as well.

added move-assignment operators for the accessors, which is required to use move-assignment operators of modules containing accessors

refactor ArrayAccessor and ScalarAccessor: split off common code and put into common base class InversionOfControlAccessor

allow determining a fully qualified name for application variables (i.e. including qualified name of owning module)

use the new readLatest(), which has been added to the latest DeviceAccess version, to implement the naturally expected behaviour when using a push-type variable with a poll-type accessor

added preliminary support for tags to application variables which can be searched for and used to generate virtual modules

fixed replacing Array and ScalarAccessors, which was broken after moving to the NDRegisterAccessorBridge-based accessors

fixed poll-type inputs using no longer non-blocking read after the switch to the NDRegisterAccessorBridge-based accessors

Rebased the ScalarAccessor and ArrayAccessor classes onto the mtca4u::NDRegisterAccessorBridge class.
Known problems present: code compiles but tests do not run

Removed the macros for defining accessors and introduced convenience classes instead. This adds slightly more syntactic sugar, but also allows more flexibility and seems to be a more coherent interface.

This commit incompatibly breaks the interface with the previous versions. Since ApplicationCore is not yet used in any productive environment, no compatibility is provided.

- Default constructor for Accessor exists now
- A function Accessor::replace() allows to assign a new accessor
- For clarity/safety: copying accessors using the assignment operator is now forbidden
- The destructor of the accessor unregisters it from the module (to allow temporary accessors)

Added description field to the variables. It is currently ignored and will be added to the XML file in a next step.
