Should fix https://bugs.freedesktop.org/show_bug.cgi?id=41613
We don't want to create these vertex elements unless the pipe driver
vertex stage can handle integers.

If there is not enough space in pushbuffer for fence emission
(nouveau_fence_emit -> nv50_screen_fence_emit -> MARK_RING),
the pushbuffer is flushed, which through flush_notify ->
nv50_default_flush_notify -> nouveau_fence_update marks currently
emitting fence as flushed. But actual emission is done after this mark.
So later when there is a need to wait on this fence and pushbuffer
was not flushed in between, fence wait will never finish causing
application to hang.
To fix this, introduce new fence state between AVAILABLE and EMITTED,
set it before emission and handle it everywhere.
Additionally obtain fence sequence numbers after possible flush in
MARK_RING, because we want to emit fences in correct order.

Note: This is a candidate for the 7.11 branch.
We need add a new set of fragment shader variants, along with new vertex
elements for signed and unsigned clears.
The new fragment shader variants are due to the integers values requiring
CONSTANT interpolation. The new vertex element descriptions are for passing
the clear color as an unsigned or signed integer value.

This adds the various mesa->gallium and gallium->mesa format conversions
along with the GL->gallium texture choosers for integers.

This add support for unsigned/signed integer types via adding a 'pure' bit
in the format description table. It adds 4 new u_format get/put hooks,
for get/put uint and get/put sint so that accessors can get native access
to the integer bits. This is used to avoid precision loss via float converting
paths.
It doesn't add any float fetchers for these types at the moment, GL doesn't
require float fetching from these types and I expect we'll introduce a lot
of hidden bugs if we start allowing such conversions without an API mandating
it.
It adds all formats from EXT_texture_integer and EXT_texture_rg.
0 regressions on llvmpipe here with this.
(there is some more follow on code in my gallium-int-work branch, bringing
softpipe and mesa to a pretty integer clean state)
v2: fixup python generator to get signed->unsigned and unsigned->signed
fetches working.

This fixes up the integer format choosing to pick the closest mesa format
then the most likely fallback.
(the formatting in this file needs cleaning in another patch).

This just adds a simple packing for GL_UNSIGNED_INT/GL_INT destination formats.
This is enough for at least the gallium drivers to pack both unsigned and signed types for read pixels.

Most of these functions used three spaces for the first level of
indentation, but four spaces for the next level. One used tabs and then
three spaces. Some used 3/4 in a then block but 3/3 in the else block.
Normally I try to avoid field days like this, but since the functions
were so inconsistent, even internally, it was making it difficult to
edit without introducing spurious whitespace changes.
So, just get it over with. git diff -b shows 0 lines changed.

i915 and i830 hardware doesn't have HiZ, so remove all HiZ related
assertions from *update_draw_buffer().
I've removed the dead format checks completely rather than replace them
with more appropriate checks. This doesn't reduce "assertion coverage",
however, because when I added these HiZ related assertions in c8fdf66
there were no pre-existing checks there.

Silences a warning about comparing to an unsigned variable. It looks like
the result of swizzle_for_size() is always assigned to unsigned vars.
