061be3d084 In Program::PerContextProgram changed const Uniform* to osg::ref_ptr<const Uniform*> to avoid the possibility of a uniform being deleted
and another being created and assigned at the same address which previously confused the uniform tracking code and introduced a bug.

ff565128af Introduced new osg::discardDeletedOpenGLObjects() methods, and usage of it in
GrpahicsContext::close() to handle cases where deletingOpenGLObjects is no possible,
such as when GraphicsWindowEmbedded is used.

4e5ce63c85 From Per Fahlberg, "Attached is a fix allowing removal of shaders from a program after it is
first compiled. It will also allow new shaders to be attached after the
program is first compiled."

175c3ce806 From Art Trevs, "File Changes:
- GL2Extensions, Program and Program.cpp

Features:
- Support for fragment output binding. (e.g. You can now specify in the fragment shader varying out vec3 fragOut; fragOut = vec3(1,0,1); to write to the fragOut variable. In your program you call glBindFragDataLocation(program, 1, "fragOut") to bind the fragOut variable with the MRT 1 - GL_COLOR_ATTACHMENT1_EXT)

- new methods Program::add/removeBindFragDataLocation Program::getFragDataBindingList

73fffe1800 Made Refernced::setThreadSafeReferenceCounting(bool) a virtual then overrode
this in various scene graph classes to ensure that the scene graph gets
updated as well as the objects that the initialial call is made from.

a1bda0dab8 Added support for per context extension string.
Note, this required adding a unsigned int context ID to the osg::isGLUExtensionSupported(,)
and osg::isGLExtensionSupported(,) functions.  This may require reimplementation
of end user code to accomodate the new calling convention.
