Don't use the shader key when forcing it.
Changing a shader key within vrend_create_shader will always force
virglrenderer to recreate the shader the next time it is looked up, so
memory usage will grow and performance will go down.
Also it is actually not needed if with each emitted back color also has a
corresponding front color is emitted. So restrict forcing two-sided coloring
to the cases where a back color is emitted without a front color, and don't
change the shader key.

When doing a blit in blit_int we use the same context that we use for drawing.
Now with qemu or crostini blits may be issued that are not issued by the guest
program so that it expects a GL_FRAMEBUFFER_SRGB state that might actually have
been clobbered.
Keep track of how GL_FRAMEBUFFER_SRGB is set when the framebuffer state is issued,
and restore its value after doing a blit via glBlitFramebuffer.

Running "make check" is quite slow if valgrind is enabled, and most of the time
failures is the result of a leak in the GL driver. Since when building packages
testing is enabled, this will make the package build fail when valgrind is

make it a configure option that also may fail if valgrind is not installed, but

few times, but more parameters are often desired.
Let's define a protocol instead. That way, more queries/operations (is "ctx

It's also possible to put the protocol in virgl_hw.h, so in theory
the guest can recieve a response directly from virglrenderer. Any

vrend_clear executes the Gallium clear command which is only called
when the whole viewport is cleared. So far mesa was doing excessive checks
on the scissors, thereby updating the scissors to framebuffer size when they
were disabled, and the according state changes were transmitted to the host.
With mesa/2037478 this was optimized away, so that not disabling the scissors
in the clear command manifested itself as a regression in a number of tests.
Keeping track of the scissor state in the hardware and disabling the scissors
before the clear is executes, and re-enabling them according to the last state
fixes this.
