7a2e40df5e Revert "gallium: add a is_dri_blit_image bool to pipe_blit_info"
This reverts commit 22a1b7c5b3.

The only use was radeonsi and it switched to PIPE_BIND_DRI_PRIME
instead.

22a1b7c5b3 gallium: add a is_dri_blit_image bool to pipe_blit_info
This indicates driver that a given blit is coming from the DRI
frontend.
This information can then be used to pick an appropriate blitting
method.

1c66de3239 gallium: add pipe_vertex_state and draw_vertex_state for display lists
The main motivation is to improve the score of viewperf13/snx.

This new interface is designed to be optimal for display lists as implemented
by the vbo module. It has much lower CPU overhead in the frontend, threaded
context, and the driver.

49337ec410 gallium: add rasterizer depth_clamp enable bit
This is required for d3d10+, which has depth_clamp always enabled
regardless of depth_clip (in contrast to OpenGL, where enabling
depth_clamp disables depth_clip). There doesn't seem to be a GL
extension for it, but it will be used for lavapipe to implement
VK_EXT_depth_clip_enable.

1c2690ec20 gallium: explicitly specify line rasterization mode
Currently, drivers infer the line rasterization mode from the
multisampling and line_smooth rasterization state. This is always
correct for OpenGL, but is subtly incorrect for DirectX 9, 10 and
Vulkan (when VK_EXT_line_rasterization is supported).

So let's allow front-ends to choose freely between rectangle and
paralellogram rendering.

The reason why there's no added cap for this, is that the implicit
selection that drivers currently do will work just as well (or more
correclty, just as subtly wrong) as before. And there's nothing
reasonable the front-ends can do to get the correct behavior, so
there's really no fall-back code to write either.

cac0191baa mesa: Store depth bounds test bounds as GLclampd
... instead of truncating to GLfloat. This seems somewhat silly since
the "clamp" part means only values [0.0, 1.0] are defined, but if the
depth buffer is Z32_UNORM then storing as GLfloat means you lose 8 bits
of depth bounds precision. This happens not to matter, yet, since swrast
classic doesn't support Z32_UNORM for depth, and the software gallium
drivers don't support EXT_depth_bounds_test. But the latter part is
about to change.
