shader to produce corresponding clip distances for hw clipping.

There are 3 changes:

1) stride is specified for each buffer, not just one, so that drivers don't
   have to derive it from the outputs

2) new per-output property dst_offset, which specifies the offset
   into the buffer in dwords where the output should be stored,
   so that drivers don't have to compute the offsets manually;
   this will also be useful for gl_SkipComponents
   from ARB_transform_feedback3

3) register_mask is removed, instead, there is start_component
   and num_components; register_mask with non-consecutive 1s
   doesn't make much sense (some hardware cannot do packing of components)

Christoph Bumiller: fixed nvc0.

v2: resolve merge conflicts in Draw and clean it up

Virtual address space put the userspace in charge of their GPU
address space. It's up to userspace to bind bo into the virtual
address space. Command stream can them be executed using the
IB_VM chunck.

This patch add support for this configuration. It doesn't remove
the 64K ib size limit thought this limit can be extanded up to
1M for IB_VM chunk.

v2: fix rendering
v3: fix rendering when using index buffer
v4: make vm conditional on kernel support add basic va management
v5: catch the case when we already have va for a bo
v6: agd5f: update on top of ioctl changes
v7: agd5f: further ioctl updates
v8: indentation cleanup + fix non cayman
v9: rebase against lastest mesa + improvement from Marek & Michel
v10: fix cut/paste bug
v11: don't rely on updated radeon_drm.h

Improves performance from cca 1 fps to 23 fps in Cogs.
This new codepath is not always used, instead, there is a heuristic which
determines whether to use it. Using translate for uploads is generally
slower than what we have had already, it's a win only in a few cases.

r600: DONE.
r700: MOSTLY (done but locks up).
Evergreen: MOSTLY (done but doesn't work for an unknown reason).

The kernel support will come soon.

This patch should prevent the crashes when some shaders are absent,

The CS checker doesn't check the regs and the state-tracker-provided values
are not to be trusted.

This also removes the hack for non-zero index bias.

It seems line loop stipple in hardware needs something I don't know, it might
need a proper geometry shader who knows.

SPI semantic indices for PS/VS are now static, so we don't
need to update spi config for every shaders combination. We can move
the functionality of r600_spi_update to r600(evergreen)_pipe_shader_ps.

Flatshade state is now controlled by the global FLAT_SHADE_ENA flag
instead of updating FLAT_SHADE for all inputs.

Sprite coord still requires the update of spi setup when
sprite_coord_enable is first changed from zero (enabled), and then
only when it's changed to other non-zero value (enabled for other input).
Change to zero (disabling) and back to the same value is handled via
global SPRITE_COORD_ENA.

New field "sprite_coord_enable" added to "struct r600_pipe_shader"
to track current state for the pixel shader. It's checked in the
r600_update_derived_state.

Also call r600_conv_pipe_prim earlier.

I have moved 'last_flush' and 'binding' from r600_bo to winsys/radeon.
The other members are now part of r600_resource.

This fixes ARB_draw_elements_base_vertex with max_index != ~0.

NOTE: This is a candidate for the 7.11 branch.

It can now override both buffer offsets and strides in additions to resources.
Overriding buffer offsets was kinda hackish and could cause issues with
non-native vertex formats.

This subclass of r600_resource doesn't contain any useful members,
so let's just use r600_resource.

This fixes piglit/fbo-generatemipmap-array.

It looks like SQ_TEX_SAMPLER_WORD0_0.TEX_ARRAY_OVERRIDE should be set
for array textures in order to disable filtering between slices,
which adds a dependency between sampler views and sampler states.

This patch reworks sampler state updates such that they are postponed until
draw time. TEX_ARRAY_OVERRIDE is updated according to bound sampler views.

This also consolidates setting the texture state between vertex and
pixel shaders.

As explained in the thread starting at [0], the internal include style
should be »#include "path/to/header.h"« for non-system includes.

v2: evergreen support

I don't set PA_SU_SC_MODE_CNTL.MULTI_PRIM_IB_ENA.
piglit/primitive-restart does pass though. Tested on RV730 and EG-REDWOOD.

This takes advantage of the new GEM_WAIT ioctl when mapping buffers.
