Add vertex shader which flips the texture upside down while blitting it.
Add argument to qemu_gl_run_texture_blit() to enable flipping.

With the upcoming dmabuf support in qemu there will be more users of the
shaders than just console-gl.c.  So rename ConsoleGLState to
QemuGLShader, rename some functions too, move code from console-gl.c to
shaders.c.

No functional change.

Clean up includes so that osdep.h is included first and headers
which it implies are not included manually.

Create a buffer for the vertex data and place vertexes
there at initialization time.  Then just use the buffer
for each texture blit.
