  Message : Minor reshuffling of directory structure in preparation of ESSL to GLSL compiler work. 1. Added include/GLSLANG which includes compiler API 2. Deleted src/include and moved the header files to the same directory as the corresponding source files 3. Modied include path to be relative to src/. I have only fixed paths for files I moved. We should fix it for all new files at least. It is much easier to see where an included file is coming from. I noticed that a few libGLESv2 source files include headers from libEGL project, which seems wrong. I think we should address this issue. Next step: move compiler source files to compiler/frontend and create two new projects compiler/glsl_backend and compiler/hlsl_backend.
