6ae1139630 Protect the _programSet in Shader with a mutex. 
This prevents thread safety issues when Shader objects are used in
multiple programs.

34336931fa Deprecated the osg::Shader::reaDShaderFile() and osg::Shader::loadShaderSourceFromFile() methods. 
Programmers should use osgDB::readRefShaderFile()/readShaderFile() instead.

161246d864 Refactored the GL object deletion management to use new osg::GraphicsObjectManager/GLObjectManager base classes, and osg::ContextData container. 
This approach unifies much of the code handling the clean up of OpenGL graphics data, avoids lots of local mutexes and static variables that were previously required,
and enables the clean up scheme to be easily extended by users providing their own GraphicsObjectManager subclasses.

b90503fdf5 Introduced new shader composition approach that utilizes #pragma requires(), #pragma import_defines() and #ifdef in GLSL to enable multiple different versions of shaders based 
on defines passed in from osg::StateSet::setDefine(..).

1a683e2f83 From Ulrich Hertlein, "Attached is a patch that introduces 'static_cast<unsigned int>' on some instances where 
the code returns '.size()' of a std::vector.  This caused some warnings when using clang++
on OS X."

26a8f63212 From Wang Rui, "In the attached files I've added the Compute Shader support for OSG, as well as serializer updates and a new osgcomputeshaders example. My submission also include a setComputeGroups() function in Program for setting compute-shader work groups, and a bindToImageUnit() function in Texture for binding textures as image variables in shaders. 
All code are tested on Windows 7 + NVIDIA GFX 570 with the latest GeForce 310.70 Driver (BETA), which could support OpenGL 4.3.

Compute shader information can be found at "http://www.opengl.org/registry/specs/ARB/compute_shader.txt"
