Introduce StatusWithMessage and StatusWithMessageReader which handle this.
It is used in DeviceModule error reporting.
This is a preparation in order that we can report errors consistently to DOOCS, in DoocsAdapter

make StatusAggregator use StatusWithMessage

it should output always status code + string
on the input side, connects to either status or status + string
corresponding string input is found automatically
NOTE: DeviceModule API change, the status output variables are
renamed from (status, message) to (status, status_message)!

update testing of DeviceModule outputs

because of API change of DeviceModule  (renamed message ->
status_message)

fix crash and improve message and test

- fix crash due to incorrect handling of cast to Derived
- improve message output
- make existing tests pass
- add test for status message of StatusAggregator

move StatusWithMessageReaderBase and Status def to ControlSystemAdapter

since it is required from ApplicationCore as well as from the adapters

Require e.g. when needing to report an exception programmatically

The previous implementation using the mutex had two issues:

1. The mutex was locked in a different thread than unlocked (DeviceModule constructor vs. handleException() thread). This results in undefined behaviour.
2. The boost::shared_mutex::lock_shared() function is not an interruption point, so applications did not terminate while waiting for initial values. (boost::latch::wait() is an interruption point.)

- testCircularDependencyFaultyFlags now uses modern AC without defining CS module and overriding defineConnections()

- Implemented but not tested yet
- All existing tests passing

- removed ExceptionHandlingDecorator::setOwnerValidity()

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

Now the writing in the DeviceModule is working.

Fixes #159

	-waitting for recovery is now outsourced in function
	DeviceModule::waitForRecovery()

	-everywhere where the function is called, the new function is now called.

Fixes #144

- All accessors come up in exception state.
- Read-accessors increase counter in init phase

Assertion is gone, but tests still failing

  - EntityOwner has individual counters for both events
  - Adapted all instances of increment/decrementDataFaultCounter
  - Not changed getDataValidity() implementation yet
  - Tests failing

wip #47: register accessor for write after open in DeviceModule if write cannot be performed in initialisation phase

change declaration of 'decrementDataFaultCounter' in 'EntityOwner' to take a bool parameter and adjust rest of the code to it
implement 'decrementDataFaultCounter' in 'ApplicationModule' according to ticket #95 -> rewrite all outputs when 'faultCounter' goes from 1 to 0

	Ticket #79
	- documentation for addRecoveryAccessor() and getRecoverySharedMutex()

  - add list with shared ptr of transferElements for recovery write
  - add shared mutex

- ConfigReader is in ApplicationCore.h, but was including ApplicationCore.h itself
- Added include guards to ApplicationCore.h, although it's not stricktly needed (all included headers have one). Might speed up complilation because it makes it easier for the parser.
