In trying to track down the new failure in #2670, I found that I could get
the flaky test set down to 4 tests, and dropping any remaining test
wouldn't trigger the failure (a bad 8x4 block in the middle of
dEQP-GLES3.functional.fbo.msaa.4_samples.r16f's render target). Disabling
gmem or bypass didn't help, and adding lots of CCU flushing didn't help.
What did help was disabling blitting, or this memset to initialize the
UBWC area after we (presumably) pull a BO out of the BO cache. My guess
is that the 2D blitter can't handle some rare set of state in the flags
buffer and emits some garbage.
I've run 8 gles3 and 7 gles31 runs with this branch now so hopefully I've got the4 right set of flakes marked for removal.

This function is responsible for completing the layout for an imported

We pass in all the parameters for setting up the layout, though freedreno
still sets a few of them up early (since it uses layout helpers in making
some decisions about the layout setup parameters that will be cleaned up
once krh's blitter work lands).
We can just bake the UBWC-goes-first delta into the slices at setup time.
I did have to fix up the resource shadowing swap path to swap the slice
fields, as it was missing and regressed the format reinterpets otherwise.

The slices table and most of the other layout fields in the
freedreno_resource moves into fdl_layout.
v2: Changes by anholt to not have duplicate fields, which was introducing
a surprising behavior change in resource layout (using the
level_linear helper before the setup of the shadowed fields)

To make PIPE_FORMATs usable from non-gallium parts of Mesa, I want to
move their helpers out of gallium. Since u_format used
util_copy_rect(), I moved that in there, too.
I've put it in a separate directory in util/ because it's a big chunk
of related code, and it's not clear to me whether we might want it as
a separate library from libmesa_util at some point.

This is a relatively minimal change to adjust all the gallium interfaces
to use bool instead of boolean. I tried to avoid making unrelated
changes inside of drivers to flip boolean -> bool to reduce the risk of
regressions (the compiler will much more easily allow "dirty" values
inside a char-based boolean than a C99 _Bool).

We'll need this for a few edge cases, like image/sampler view that uses
a format that UBWC does not support with a resource originally created
in a format that UBWC does support.
NOTE we *could* in some cases do an in-place uncompress. But that has
a couple potential sharp edges:
1) the uncompressed buffer could have different layout, ie. a5xx
with meta and pixel data of layers/levels interleaved.
2) if it comes mid-batch, it would force flush, or somehow fixing
up cmdstream for draws already emitted. But with the resource
shadowing approach we can rely on batch re-ordering to avoid
splitting things.. older draws see the older compressed version,
newer draws see the new uncompressed version of the rsc.

There are still some fallbacks we'll need to handle before we can enable
UBWC by default. I think we may need to fallback to uncompressed if
image atomic operations are used. And we still need to sort out how to
handle image and sampler views of compressed resources if the image/
sampler view is using a format that does not support compression. (I
think the latter should hopefully be uncommon outside of deqp/piglit.)
But at least this gets us to the point where supertuxkart works properly
with UBWC enabled ;-)

Previously we tried to normalize nr_samples to MAX2(1, nr_samples) to
avoid having to deal with 0 vs 1 everywhere. But this causes problems
in mesa/st, for example st_finalize_texture() will think there is a
nr_samples mismatch and recreate the texture. Somehow this manifests
as corrupt x11 font rendering on generations that do not support MSAA
(but apparently works fine on a5xx and a6xx which do support MSAA.)
