Removed obsolete localValidity.

- Removed extra exception handling from TriggerFanOut. It is all done by the ExceptionHandlingDecorator
- ExceptionHandlingDecorator does not drop out of testable mode until the device is initialised.

wip: changed constructor of ExceptionHandlingDecorator to have a VariableNetworkNode as argument instead of a bunch of details

It is now inferred from the TransferType in doPostRead of the
MetaDataPropagatingRegisterAccessor, if the owning module's
version number gets updated.

Rearranged processing of fanouts and their consuming nodes. A list of
consuming nodes and implementations is passed to the fanout constructors,
so the nodes don't have to added later. This resolves conflicts in the
order in which accessors are decorated and added to the fanouts.

FanOut constructors could still use refactoring.

- removed ExceptionHandlingDecorator::setOwnerValidity()

- removed DeviceModule::waitForRecovery()
- ExceptionHandlingDecorator is throwing to skip transfers

Ongoing refactoring. Consuming fanout works again.

This reverts commit d025bb5a.

This reverts commit b7fb1f68.

- doPostRead() only updates user buffer when it should
- doPostRead() sets data validity and version number
- write() returns false (no data lost), because dropping the data is intentional
- implemented interrupt()

fix: TestableModeAccessorDecorator::preRead() always released the lock and did not delegate the call to the target

ConstantAccessor not pushes the value to the queue yet

This partly reverts d5ab1447, where the existing doReadTransfer overrides
were removed. This commit gets the existing implmentations back, but
changes the function name to doReadTransferSynchronously.
