"A variable could be qualified as both readonly and writeonly,

Namely: currently we use an invalid fd of -1 for our calls to

At the same time applications (like flatland) may rely on it being
a valid one. Thus as they attempt to query the timestamp of the fence,
they get unexpected results/behaviour.

In the case of flatland - the benchmark hang inside getSignalTime().

Make use of the out fence and pass the correct fd to Android.

This patch consolidates many potential `#ifdef ANDROID` messes

hack. The hack is an `#ifdef ANDROID` in vk_android_native_buffer.h

i965: Use prepare_external instead of make_shareable in setTexBuffer2

The setTexBuffer2 hook from GLX is used to implement glxBindTexImageEXT
which has tighter restrictions than just "it's shared".  In particular,
it says that any rendering to the image while it is bound causes the
contents to become undefined.  This means that we can do whatever aux
tracking we want between glxBindTexImageEXT and glxReleaseTexImageEXT so
long as we always transition from external in Bind and to external in
Release.

The fact that we were using make_shareable before was a problem because
it would resolve away 100% of the aux data and then throw away our
reference to the aux buffer.  If the aux data was shared with some other
application (i.e. if we're using I915_FORMAT_MOD_Y_TILED_CCS) then we
would forget that the aux data even existed for the rest of eternity.
This is fine for the first frame but any subsequent calls to
glxBindTexImageEXT would bind the texture as if it has no aux
whatsoever and no resolves would happen and texturing would happen as if
there is no aux.  This was causing rendering corruption in mutter when
running on top of X11 with modifiers.

i965/tex_image: Reference the renderbuffer miptree in setTexBuffer2

The old code made a new miptree that referenced the same BO as the
renderbuffer and just trusted in the memory aliasing to work.  There are
only two ways in which the new miptree is liable to differ from the one
in the renderbuffer and neither of them matter:

 1) It may have a different target.  The only targets that we can ever
    see in intelSetTexBuffer2 are GL_TEXTURE_2D and GL_TEXTURE_RECTANGLE
    and the difference between the two doesn't matter as far as the
    miptree is concerned; genX(update_sampler_state) only looks at the
    gl_texture_object and not the miptree when determining whether or
    not to use normalized coordinates.

 2) It may have a very slightly different format.  Again, this doesn't
    matter because we've supported texture views for quite some time so
    we always look at the gl_texture_object format instead of the
    miptree format for hardware setup anyway.

On the other hand, because we were recreating the miptree, we were using
intel_miptree_create_for_bo which doesn't understand modifiers.  We
really want this function to work without doing a resolve so long as you
have modifiers so we need to fix that.

BRW_NEW_BLORP for a bunch of SURFACE_STATE setup code, including render
targets, on the basis that blorp invalidates binding tables but not

are not uploading new render target surface states after allocating
new CCS_D surfaces for fast clears (which allocation is deferred until
an actual clear occurs).

The reason this only fails in BDW is that on SKL+ we use CCS_E which
is allocated up front so it exists in the initial surface state, the
problem can be reproduced in these platforms too if we use
INTEL_DEBUG=norcb to force the CCS_D path.
