i965: s/Tungsten Graphics/VMware/ in brw_bufmgr.c.

In commit 877128505431adaf817dc8069172ebe4a1cdf5d8, José replaced the
Tungsten Graphics copyright notices with VMware, as Tungsten is gone.

This commit does the equivalent of José's change to the new file.

i965: Reformat the copyright header in brw_bufmgr.c

This reformats the copyright header to match what we use in most of the
newer parts of the driver.  There are a few minor alterations: we change
"COPYRIGHT HOLDERS, AUTHORS AND/OR ITS SUPPLIERS" to the standard
"AUTHORS OR COPYRIGHT HOLDERS", and move the permission notice to the
proper place (it should be in the middle, so "next paragraph" actually
refers to something).

Both of these changes match the OSI's MIT License text:

radeonsi: update dirty_level_mask only when flushing or unbinding framebuffer

This fixes corruption with bindless textures in Dawn Of War 3.

The do_update_surf_dirtiness mechanism was complicated and dirty_level_mask
was only updated after the first draw call. The problem is bindless textures
are checked for decompression every draw call and we would only decompress
after the first draw call. The solution is to set dirtiness after the last
draw call to the framebuffer, so the (unconditional) decompression of
bindless textures happens at the right time.

egl: move KHR_no_error vs debug/robustness check further down

We'll fail to flag an error if the context flags appear after the
no-error attribute in the context attribute list.

Delay the check to after attribute parsing to fix this.

radeonsi/gfx9: reduce max threads per block to 1024 on gfx9+

The number of supported waves per thread group has been reduced to 16
with gfx9. Trying to use 32 waves causes hangs, and barriers might
not work correctly with > 16 waves.

radeonsi: fix detection of DRAW_INDIRECT_MULTI on SI

The firmware version numbers for SI were wrong. The new numbers are probably
too conservative (we don't have a definitive answer by the firmware team),
but DRAW_INDIRECT_MULTI has been confirmed to work with these versions on
Tahiti (by Gustaw) and on Verde (by myself).

While this is technically adding a feature, it's a feature we thought we had
for a long time. The change is small enough and we're early enough in the 17.2
release cycle that it should still go in.

anv: only expose up to 28 vertex attributes

The EU limit of 128 GRFs should allow 32 vertex elements of 4 GRFs.
However, the maximum allowed value of "Vertex URB Entry Read Length"
in SIMD8 is 15. And 15 * 8 = 120 gives us a limit of 30 vertex elements.
Because we also need to reserve a vertex buffer to upload
VertexIndex/InstanceIndex and another to upload DrawID when needed,
we can only expose 28.
