ea9f479674 Attempt to fix broken DLL exports from osgDB 
Only export the osgDB method implementations, instead of the entire
class, and hence avoid exporting symbols from the base class, which
then conflict with other compilation units when linking.

This avoids the need for /FORCE:MULTIPLE linker option with MSVC.

da47f8a156 Adds an indexMesh option to disable mesh reindexation 
This mainly breaks gles/osgjs when stripifying a MorphGeometry. It also
usually doesn't make sense to reindex an already indexed mesh.

fe6238d126 Added osg::GraphicsContext::WindowingSystemInterfaces singleton for managing multiple WIndowinSystemInterface 
implementations being registered at the same time.

One usage case for this functionality to support usage of Wayland and X11 in the same version of the osgViewer.

As part of the new functionality there is now a osg::GraphicsContext::Traits::windowingSystemPreferrence string
that default to empty, but if defined will ensure that a specific WindowingSystemInterface is utilized when
you do a generic call like osg::createGraphicsContext().

Also implemented is standard proxy object for registering the new contexts and removing them automatically, and
declaration of standard graphicswindow_name() C entry point to help with static build linking.

68430ee8e5 Added a local implementation of SlideEventHandler::checkNeedToDoFrame() so that Present3D can toggle on/off the need for continuous rendering to only slides that require it, 
enabling slides with no animation to sit iddle rather keeping rendering, reducing CPU/GPU overhead and saving power.

f5b5202296 From Joe Thompson, "OpenSceneGraph cannot be built with Visual Studio 2008. 
The file osg-OpenSceneGraph-3.4.0\include\osg\Types
typedefs int8_t, int16_t, int32_t and int64_t
These are typedefed as signed __intX in several other places.
With VS2008, this causes an error "int8_t redifined, different basic types"
Explicitly declaring them signed fixes the error."

5d03bb9a2b From Jannik Heller, "This submission fixes a stuttering issue that may occur when occlusion query nodes are in view. The problem is that OSG retrieves the occlusion query result without first checking if it's available (GL_QUERY_RESULT_AVAILABLE). Thus, the driver has to sync with the GPU i.e. wait for all queued draw calls to complete. This is particularly bad in V-Synced situations where the driver may be using multi frame queueing techniques - coupled with the fact that OSG only runs an occlusion query every 5th frame, results in very unpleasant stuttering in some situations. 
The change I made is to check GL_QUERY_RESULT_AVAILABLE before retrieving the query, to ensure that there won't be a stall. If the query result is not available yet, we'll leave it alone and try again in the next frame.

Had to make a few more changes than I'd liked, mostly because the TestResult mechanism wasn't designed for holding on to query objects for more than one frame. As well, I'm thinking that RetrieveQueriesCallback and ClearQueriesCallback could be merged together, if we wanted to go for more refactoring. For though now my strategy is to make as little changes as possible. Let me know what you think of the patch."
