Removed OpenCL/D3D11 specialization and add DEVICE_CONTEXT as a template parameter. For the kernels which don't need a context object (e.g. CPU, OpenGL, cuda) just ignore the context, and for the kernels which use a context (e.g. OpenCL, DirectX) takes a context or a user-defined class as which encapsulates device contexts. Note that OpenCL requires two objects, cl_context and cl_command_queue. The user-defined class must provide GetContext() and GetCommandQueue() for strongly typed binding to osd VertexBuffers and ComputeContexts. Osd::Mesh and MeshInterface have been used as a handy harness to host multiple GPU kernels and graphics APIs. However it has CL/DirectX specializations and duplicates large amount of plubming code. With this change, glMesh.h and d3d11Mesh.h become just typedefs and all logic is put into mesh.h without specializations. Also cleaned up unused header files and code formatting.
