ioemu: SDL rendering using OpenGL
Add opengl support for rendering the guest framebuffer in the SDL
window. SDL is needed anyway to open the window and handle the
events. Opengl rendering is optional and can be turned off at both
compile time and in the vm configuration file.
Some of the benefits of using opengl are:
- faster rendering, less CPU intensive, especially with good graphic
cards;
- makes the window resizing possible and hardware accelerated, thus
very efficient and smooth;
- allows other optimizations like sharing directly a buffer in vram
with the guest (not yet implemented).
