2018-05-18sdl: Move use of surface pointer below check for whether it is NULLPeter Maydell
In commit 2ab858c6c38ee1 we added a use of the 'surf' variable in sdl2_2d_update() that was unfortunately placed above the early-exit-if-NULL check. Move it to where it ought to be.

2018-02-16sdl: restore optimized redrawAnatoly Trosinenko
The documentation on SDL_RenderPresent function states that "the backbuffer should be considered invalidated after each present", so copy the entire texture on each redraw. On the other hand, SDL_UpdateTexture function is described as "fairly slow function", so restrict it to just the changed pixels. Also added SDL_RenderClear call, as suggested in the documentation page on SDL_RenderPresent.

Add a new sdl2_2d_redraw function for a complete screen refresh, so we can stop using graphic_hw_invalidate for that. There is no need to bother console / gfx emulation code if we are just going to re-blit the screen after window resizes.
