OpenGL ES does not support conversion from the given data format
to the internal format with glTexImage2D.
Use the given data format as the internal format, and ignore
the given alpha channels with GL_TEXTURE_SWIZZLE_A in case the
format contains alpha channels.

In a GVT-g setup with dmabuf and GTK GUI, the current 2D texture at
surface_gl_update_texture is not necessarily
surface->texture. Adding a glBindTexture fixes related crashes and
artifacts, and is generally more secure.

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.
