Robostness FBObject / GLReadBufferUtil: Ignore pre-existing GL errors - remove GL error checking in FBObject bind/unbind.
- User GL code caused errors shall not fail impl. - FBObject bind/unbind GL error checking is almost useless due to it's simple code, would only catch user GL code errors, which should be ignored here. - MultisampleDemoES2: Only enable GL_MULTISAMPLE if available, i.e. validate passed multisample flag
