Yf/Ys tiling never got used in i965 due to not delivering
the expected performance benefits. So, this patch is deleting
this dead code in favor of adding it later in ISL when we
actually find it useful. ISL can then share this code between
vulkan and GL.

Fast copy blit was primarily added to support Yf/Ys detiling.
But, Yf/Ys tiling never got used in i965 due to not delivering
the expected performance benefits. Also, replacing legacy blits
with fast copy blit didn't help the benchmarking numbers. This
is probably due to a h/w restriction that says "start pixel for
Fast Copy blit should be on an OWord boundary". This restriction
causes many blit operations to skip fast copy blit and use legacy
blits. So, this patch is deleting this dead code in favor of
adding it later when we actually find it useful.

We've already required Kernel 3.6 on Gen6+ since Mesa 9.2 (May 2013,
commit 92d2f5acfadea672417b6785710c9e8b7f605e41). It seems reasonable
to require it for Gen4-5 as well, bumping the requirement from 2.6.39.
This is necessary for glClientWaitSync with a timeout to work, which
is a feature we expose on Gen4-5. Without it, we would fall back to an
infinite wait, which is pretty bad.
See kernel commit 172cf15d18889313bf2c3bfb81fcea08369274ef in 3.6+.

This doesn't really "do" anything because the default tiling for the
winsys buffer is X tiled. We do however want the X tiled modifier to
work correctly from the API perspective, which would imply that if you
set this modifier, and later do a get_modifier, you get back at least X
tiled.

This patch begins introducing how we'll actually handle the potentially
many modifiers coming in from the API, how we'll store them, and the
structure in the code to support it.
Prior to this patch, the Y-tiled modifier would be entirely ignored. It
shouldn't actually be used until this point because we've not bumped the
DRIimage extension version (which is a requirement to use modifiers).
Measuring later in the series with kmscube:
Linear:
Read bandwidth: 1048.44 MiB/s
Write bandwidth: 1483.17 MiB/s
Y-tiled:
Read bandwidth: 471.13 MiB/s

At image creation create a path for dealing with the linear modifier.
This works exactly like the old usage flags where __DRI_IMAGE_USE_LINEAR
was specified.
During development of this patch series, it was decided that a lack of
modifier was an insufficient way to express the required modifiers. As a
result, 0 was repurposed to mean a modifier for a LINEAR layout.
NOTE: This patch was added for v3 of the patch series.
v2: Rework the algorithm for modifier selection to go from a bitmask
based selection to this priority value.
v3: Make DRM_FORMAT_MOD_INVALID allowed at selection as a way of
identifying no modifiers found (because 0 is LINEAR) (Jason)
v4: Remove the logic to prune unknown modifiers (like those from other
vendors) and simply handle is in select_best_modifier (Jason)

New to the patch series after reordering things for landing smaller
chunks.
This will essentially enable modifiers from clients that were just
enabled in previous patches. A client could use the modifiers by
setting all of them at create, but had no way to actually query them
after creating the surface (ie. stupid clients could be broken before
this patch, but in more ways than this).
Obviously, there are no modifiers being actually stored yet - so this
patch shouldn't do anything other than allow the API to get back 0 (or
the LINEAR modifier).

This deletes all of our handwritten code in favor of autogenerated
genxml-based decoding. This should be much more usable, as the old
code isn't entirely accurate - we updated some things for new
generations, but not everything.
Aubinator has one annoying limitation: it has no idea how many entries
to print when encountering e.g. 3DSTATE_BINDING_TABLE_POINTERS_VS. It
picks an arbitrary number, which may skip decoding valid data, and may
print extra garbage entries.
We do a better job here by making brw_state_batch track the size of the
data stored at a particular batchbuffer offset. Then, we can divide by
the structure size to obtain the exact number of entries.

This should give substantially better decoding, as the public libdrm
decoder hasn't been properly maintained in years.
For now, we reuse the existing state dumping mechanism. We'll improve
that in the next patch.
To avoid increasing the size of the driver, we restrict this feature
to debug builds of Mesa. There's probably very little use for it in
release builds anyway.

Detecting register write support by trial and error introduces a
stall at screen creation time, which it would be nice to avoid.
Certain command parser versions guarantee this will work (see the
giant comment in intelInitScreen2 below, or a few commits ago):
- Ivybridge: version >= 1 (kernel v3.16)
- Baytrail: version >= 2 (kernel v3.19)
- Haswell: version >= 7 (kernel v4.8)
For simplicity, we don't bother with version 1 in this patch.
This assumes that the user hasn't disabled aliasing PPGTT via a kernel
command line parameter. Don't do that - you're only breaking things.

If we can't write registers, then the effective command parser version
is 0 - it may exist, but it's not usefully enabling anything.
See kernel commit 1ca3712ca3429a617ed6c5f87718e4f6fe4ae0c6 (in v4.8)
where the kernel starts doing this for us. This makes us do more or
less the same thing on older kernels.
This should preserve a bit of sanity by allowing us to perform a
screen->cmd_parser_version > N check to determine that we really can
use the features promised by command parser version N.

In commit d2590eb65ff28a9cbd592353d15d7e6cbd2c6fc6 I enabled GL 4.5
on Haswell...but failed to check if we could do indirect compute
shader dispatch...and query buffer objects.
Indirect compute shader dispatch requires command parser version 5
(kernel commit 7b9748cb513a6bef4af87b79f0da3ff7e8b56cd8, which is in
Linux v4.4). On earlier kernels we would have disabled
ARB_compute_shader, which is a mandatory part of OpenGL 4.3+.
Query buffer objects currently require MI_MATH and MI_LOAD_REGISTER_REG,
which mean command parser version 7 (Linux v4.8). On earlier kernels
we would have disabled ARB_query_buffer_object, which is a mandatory
part of OpenGL 4.4+.
The new version support looks like:
- Kernel 4.1 and older => OpenGL 3.3
- Kernel 4.2-4.3 => OpenGL 4.2
- Kernel 4.4-4.7 => OpenGL 4.3
- Kernel 4.8+ => OpenGL 4.5

Prior to Skylake the Gen HW timestamps were driven by a 12.5MHz clock
with the convenient property of being able to scale by an integer (80)
to nanosecond units.
For Skylake the frequency is 12MHz or a scale factor of 83.333333
This updates gen_device_info to track a floating point timebase_scale
factor and makes corresponding _queryobj.c changes to no longer assume a
scale factor of 80 works across all gens.
Although the gen6_ code could have been been left alone, the changes
keep the code more comparable, and it now shares a few utility functions
for scaling raw timestamps and calculating deltas. The utility for
calculating deltas takes into account 32 or 36bit overflow depending on
the current kernel version.
Note: this leaves the timestamp handling of ARB_query_buffer_object
untouched, which continues to use an incorrect scale of 80 on Skylake
for now. This is more awkward to solve since the scaling is currently
done using a very limited uint64 ALU available to the command parser
that doesn't support multiply or divide where it's already taking a
large number of instructions just to effectively multiple by 80.
This fixes piglit arb_timer_query-timestamp-get on Skylake
v2: (Ken) Update timebase_scale for platforms past Skylake/Broxton too.

Mostly a dummy git mv with a couple of noticable parts:
- With the earlier header cleanups, nothing in src/intel depends
files from src/mesa/drivers/dri/i965/
- Both Autoconf and Android builds are addressed. Thanks to Mauro and
Tapani for the fixups in the latter
- brw_util.[ch] is not really compiler specific, so it's moved to i965.
v2:
- move brw_eu_defines.h instead of brw_defines.h
- remove no-longer applicable includes
- add missing vulkan/ prefix in the Android build (thanks Tapani)
v3:

Split out the EU defines from the 'generic' ones, as the former are more
compiler oriented.
With a later commit we'll move brw_eu_defines.h alongside the compiler
infra to src/intel/. Pulling all the defines in there seems overzealous.
Some defines are used by both i965 and the i965 compiler. Those are
moved to brw_eu_defines.h, and annotated accordingly. The i965 users
were updated to have the extre include to indicate that.
With future work we might provide a better, split but for now this seems
reasonable.
