Use caps to obtain the multisample sample positions for up to 16
positions and implement the according Gallium interface.

v2: remove unrelated chunk (thanks Ilia Mirkin)

v3: - also return positions for intermediate sample counts
    - fix unused varible warning

Add support for glsl 'invariant' modifier for output data declarations.
Gallium drivers that use TGSI serialization currently loose invariant
modifiers in glsl shaders.

Tested: chromiumos on qemu with virglrenderer.

Virgl could save a lot of work converting buffers in the host side
between formats if Mesa supported a bunch of other formats when reading
pixels.

This commit adds cases to handle specific formats so that the values
reported by the two calls match more closely the underlying native
formats.

In GLES is important that IMPLEMENTATION_COLOR_READ_* return the native
format and data type because the spec only allows reading with those,
besides GL_RGBA or GL_RGBA_INTEGER.

Additionally, because virgl currently doesn't implement such
conversions, this commit fixes several tests in
dEQP-GLES3.functional.fbo.color.clear.*, when using virgl in the guest
side.

The logic is based on knowledge that is shared with
_mesa_format_matches_format_and_type() but we cannot assert that the
results match as we don't have all the starting information at both
points. So leave the assert out and hope CI comes soon to save us all.

v2: * Let R10G10B10A2_UINT fall back to GL_RGBA_INTEGER (Eric Anholt)
    * Assert with _mesa_format_matches_format_and_type (Eric Anholt)

v3: * Remove the assert, as it won't be reliable (Eric Anholt)

and PIPE_FORMAT_R8G8B8A8_SRGB, as well.

The reason for this is that when Virgl runs with GLES on the host, it
cannot directly upload textures in BGRA.

So to avoid a conversion step, consider the RGB sRGB formats as well for
this extension.

If the driver doesn't support PIPE_FORMAT_B8G8R8A8_SRGB, fall back to
PIPE_FORMAT_R8G8B8A8_SRGB.

Drivers such as Virgl will have a hard time supporting
PIPE_FORMAT_B8G8R8A8_SRGB when the host runs GLES, as GL_ABGR isn't as
well suported there.

So go with PIPE_FORMAT_R8G8B8A8_SRGB so these drivers can avoid a
conversion copy.

When Mesa itself implements ETC2 decompression, it currently
decompresses to formats in the GL_BGRA component order.

That can be problematic for drivers which cannot upload the texture data
as GL_BGRA, such as Virgl when it's backed by GLES on the host.

So this commit adds a flag to _mesa_unpack_etc2_format so callers can
specify the optimal component order.

In Gallium's case, it will be requested if the format isn't in
PIPE_FORMAT_B8G8R8A8_SRGB format.

For i965, it will remain GL_BGRA, as before.

For instruction sequences that change the address register with every load
the current limit to bail out of the scheduler and reject the optimisation
was too tight, i.e. it was expected that at least one pending instruction
would be scheduled each time.

Give the scheduler more margin to sort out these load sequences by allowing
a number of rounds where no instruction is scheduled.

Dave Airlie:

 "A bunch of CTS tests led me to write
  tests/shaders/ssa/fs-while-loop-rotate-value.shader_test
  which r600/sb always fell over on.

  GCM seems to move some of the copies into other basic blocks,
  if we don't allow this to happen then it doesn't seem to schedule
  them badly.

  Everything I've read on SSA/phi copies say they have to happen
  in parallel, so keeping them in the same basic block seems like
  a good way to keep some of that property."

This patch differs from the one proposed by Dave in that it only adds
the NF_DONT_MOVE flag to copy_move instructions that are created by split_phi*
and that are located in loops.

Fixes piglit: tests/shaders/ssa/fs-while-loop-rotate-value.shader_test
(no regressions in the shader set). It also fixes all failing tests from

  dEQP-GLES3.functional.shaders.loops.*

This extension provides fences and frame count information to direct
display contexts. It uses new kernel ioctls to provide 64-bits of
vblank sequence and nanosecond resolution.

v2:
	Rework fence integration into the driver so that waiting for
	any of a mixture of fence types (wsi, driver or syncobjs)
	causes the driver to poll, while a list of just syncobjs or
	just driver fences will block. When we get syncobjs for wsi
	fences, we'll adapt to use them.

v3:	Adopt Jason Ekstrand's coding conventions

	Declare variables at first use, eliminate extra whitespace between
	types and names. Wrap lines to 80 columns.

v4:	Adapt to WSI fence API change. It now returns VkResult and

	use the default allocator when NULL is provided, so remove the
	computation of 'alloc' here.

v6:

    Also change the WSI fence wait function to take only absolute

    users wanted relative timeouts, and it's simpler if that option
    isn't available.

    Terminate the DPMS property loop once we've found the property.

Handle the case where the set of fences to wait for is not all of the
same type by either waiting for them sequentially (waitAll), or
polling them until the timer has expired (!waitAll). We hope the
latter case is not common.

While the current code makes sure that it always has fences of only
one type, that will not be true when we add WSI fences. Split out this
refactoring to make merging that clearer.
