Qt used to store the GL extensions a particular implementation supported in a global cache, which was initialized once and never updated. This could cause problems because different types of context might support different kinds of extensions (e.g. the difference between sw and hw contexts). With this patch, the GL extensions are cached and updated within each QGLContext. It also makes the extension initialization lazy, which saves application initialization costs for embedded platforms. The patch introduces a internal cross platform QGLTemporaryContext class that is used to create a light-weight GL context without going via QGLWidget and friends (QWS and WinCE still have QGLWidget fallbacks for now).
