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.

Remove functions that do not exist anymore

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

This reverts commit 4f2b35be.

Was actually used and tested.

this was never really a problem, since it was always used with the BidirectionalProcessArray() which implements writeDestructively same as write

It already exists for ArrayAccessor::readAsync()...

transform logic_errors in doXxxTransferYyy that are already checked in the preXxx functions into asserts

Fixes #153

Now the writing in the DeviceModule is working.

Fixes #159

* doGenericPostAction is void
* removed endless loop in doGenericPostAction
* only wait for recovery if application is running in multi-threaded mode
* fixed return value for doReadTransferXxx in case transfer is not allowed
