svga: re-validate sampler view at draw time if needed

This patch validates those sampler views with backing copy
of texture whose original copy has been updated since the
view is last validated.
This is done here at draw time because the texture binding might not
have modified, hence validation is not triggered at state update time,
and yet the texture might have been updated in another context, so
we need to re-validate the sampler view in order to update the backing
copy of the updated texture.

This fixes a rendering flickering issue with Photoshop running in
Linux VM with HWversion 11. The problem is Photoshop renders to texture A
in context X, and then bind texture A to context Y. The first time
when texture A is bound to context Y, cso calls pipe->set_sampler_views().
Validation of sampler views is done, rendering is fine.
But when texture A is rendered to again in context X, and rebound in
context Y, cso skips pipe->set_sampler_views() because texture A is already
bound in context Y. SVGA driver is not given a chance to re-validate
the texture binding, the backing copy of the texture is not updated,
and hence causes black image.

mesa: Require mipmap completeness for glCopyImageSubData() at times.

This patch makes glCopyImageSubData require mipmap completeness when the
texture object's built-in sampler object has a mipmapping MinFilter.
This is apparently the de facto behavior and mandated by Android's CTS.

One exception is that we ignore format based completeness rules
(specifically integer formats with linear filtering), as this is
also the de facto behavior that until recently was mandated by the
OpenGL 4.5 CTS.

This was discussed with both the OpenGL and OpenGL ES working groups,
and while everyone agrees this behavior is unfortunate and complicated,
it is what it is at this point.  There was little appetite for relaxing
restrictions given that all conformant Android drivers followed the
mipmapping rule, and all conformant GL 4.5 implementations ignored the
integer/linear rule.

etnaviv: fix shader miscompilation with more than 16 labels

The labels array may change its virtual address on a reallocation, so
it is invalid to cache pointers into the array. Rather than using the
pointer directly, remember the array index.

i965/dri: Support R8G8B8A8 and R8G8B8X8 configs

The Android framework requires support for EGLConfigs with
HAL_PIXEL_FORMAT_RGBX_8888 and HAL_PIXEL_FORMAT_RGBA_8888.

Even though all RGBX formats are disabled on gen9 by
brw_surface_formats.c, the new configs work correctly on Broxton thanks
to _mesa_format_fallback_rgbx_to_rgba().

On GLX, this creates no new configs, and therefore breaks no existing
apps. See in-patch comments for explanation. I tested with glxinfo and
glxgears on Skylake.

On Wayland, this also creates no new configs, and therfore breaks no
existing apps. (I tested with mesa-demos' eglinfo and es2gears_wayland
on Skylake). The reason differs from GLX, though. In
dri2_wl_add_configs_for_visual(), the format table contains only
B8G8R8X8, B8G8R8A8, and B5G6B5; and dri2_add_config() correctly matches
EGLConfig to format by inspecting channel masks.

On Android, in Chrome OS, I tested this on a Broxton device. I confirmed
that the Google Play Store's EGLSurface used HAL_PIXEL_FORMAT_RGBA_8888,
and that an Asteroid game's EGLSurface used HAL_PIXEL_FORMAT_RGBX_8888.
Both apps worked well. (Disclaimer: I didn't test this patch on Android
with Mesa master. I backported this patch series to an older Android
branch).
