* AbstractImageReader is now again an AbstractProcessor, so that we can get rid of the dynamic_casts in GenericImageReader
* DevilImageReader is no longer a VisualizationProcessor but gets the OpenGL context through OpenGLJobProcessor::ScopedSynchronousGlJobExecution
* Fixed alglib's CMakeLists.txt

3d mi segment flat rebased

campvis-test does not use OpenGLJobProcessor and only initializes it halfway. However, some CAMPVis functionality relies on that. Therefore, I introduced a hack/workaround to set the OpenGL thread manually if you need to.

Furthermore, added exit(EXIT_FAILURE) to recursive assertions to avoid possible endless assertion loops in campvis-test (and thus amok running jobs in Jenkins).

* Fixed possible endless loop in event evaluation of AbstractPipeline.
* Fixed 4-channel image rendering in datacontainerinspector.frag.

* Added OpenGL thread guard to image conversions to ImageRepresentationGL.

[merged commit]clean ups, fixes for g++ errors and warnings, and edits for cppcheck errors (except for the 480+ in the external library AlgLib)

Various fixes

See merge request !91

The VolumeExplorer has now an additional property defining which view is shown in the big section (and which in the three small sections). Hence, now it is also possible to show one of the slice views in large and have the volume rendering in small.

To better support sharing the functionality of slice rendering, the SliceExtractor processor was refactored: Similar to the RaycastingProcessor, the main functionality was moved to an abstract base class, the SliceRenderProcessor. This takes care of computing all the necessary transformation matrices, optionally rendering crosshair and integrating geometry, as well as handling user input to support scribbling. The actual SliceExtractor processor now only implements the rendering of the slice itself, i.e. applying the transfer function.

In this regard, VolumeExplorer was updated to use the generic SliceRenderProcessor, and TransFuncWindowingEventListener supports changing of its assigned property.

Replaced DataContainer::s_dataAdded<const std::string&, DataHandle> with DataContainer::s_dataAdded<std::string, DataHandle>.

According to Visual Leak Detector, CAMPVis is now memory leak free. :)

Memory pools

* Fixed includes in sigslot.cpp
* Implemented memory pools also for AbstractJob using the pool of OpenGLJobProcessor

Async signals

See merge request !87

refs #384

* Slight changes to the API: renamed signal::trigger() to signal::triggerSignal() and signal::queue() to signal::queueSignal()
* Replaced all sigslot signal emits through operator() with emits through emitSignal() to enable debug feature.
* Fixed a possible race condition when deleting a GeometryTransferFunction and its editor window at the same time (as this will happen from different threads).

refs #384

When compiled with CAMPVIS_DEBUG, all signals carry additional information on the calling function, file and line. This is realized transparently through some macro magic when client code emits signals through the new emitSignal() method. Unfortunately, there is no way to debug-overload the operator(), hence, while this way of emitting signals remains valid, it cannot write the debug information into the signal handle.

To avoid symbol conflicts, _connection_base::emitSignal() and has_slots::emitSignal() had to be renamed to ::processSignal().

refs #384

Introducing SignalHandlingMode to signal_manager to allow forcing all signals being handled directly (needed for test-campvis) or queued.

Itksegmentation rescale

1. Rescaling was needed for restricting the intensity values of images used in segmentation to [0,255]. Some images were exceeding this range.

2. Corrected copyright year range.

Volume explorer mouse event - Y coordinates

Small correction:  Y coordinates of the render size should be used instead of X coordinates when subtracting from me->y().

See merge request !85

* Fixed crash (due to nullptr) in DataContainerInspectorWidget if DevIL module not present.

refs #384

* Updated sigslot::concurrent_pointer_list::insert() and sigslot::concurrent_pointer_list::push_back() to fill holes where items already have been deleted. This avoids degrading performance due to excessive fragmentation.
* Updated sigslot legal header.

Updated sigslot::concurrent_pointer_list implementation as well as added several typename declarations to calm down GCC.
