Use proper ARB_framebuffer_object extension. 

Separated EXT_framebuffer_object, EXT_framebuffer_blit,
EXT_framebuffer_multisample and EXT_packed_depth_stencil don't have the
same functionality as ARB_framebuffer_object (e.g. missing
GL_FRAMEBUFFER_UNDEFINED in glCheckFramebufferStatus()) and separated
read/draw binding is only in EXT_framebuffer_blit, which complicates the
internals.

Checked with Mesa 8/9 and OpenGL 2.1, current one has
ARB_framebuffer_object and also all these four, Mesa 7.7 didn't have
EXT_framebuffer_multisample, but that's a long time ago, so not
supporting these separate extensions shouldn't be an issue.

The problem with unavailable separate binding points remains on OpenGL
ES 2.0, there are three different extensions bringing that
functionality, thus the code managing the available binding points
remains there.
