From section E.1 (Profiles and Deprecated Features of OpenGL 3.0)
of the OpenGL 3.0 spec:
"LineWidth is not deprecated, but values greater than 1.0
will generate an INVALID VALUE error"
From context it is clear that values greater than 1.0 should only
generate an INVALID VALUE error in a forward-compatible context.
The code was correctly quoting this spec text, but it was disallowing
all line widths in forward-compatible contexts, instead of just widths
greater than 1.0.
This patch introduces the correct check, so that setting a line width
of 1.0 or less is permitted.

Otherwise, blits to the window system buffer may cause crashes,
since dst_irb->mt may be NULL.
This code is lifted straight out of brw_blorp_framebuffer()'s
try_blorp_blit() helper.
Fixes crashes in Piglit's fbo-sys-blit on systems without BLORP.

This prevents a crash in a future patch.
_mesa_initialize_context() creates a default transform feedback object
by calling the NewTransformFeedbackObject() driver hook. Eventually,
we'll want to subclass that and allocate a buffer object. This means
passing brw->bufmgr to drm_intel_alloc_bo(), and crashing if it isn't
initialized yet.
The buffer manager is actually already initialized; we just hadn't
copied the pointer from intel_screen to intel_context quite early
enough.

Gen7+ supports four transform feedback streams. Using a function-like
macro makes it easy to access them by stream number or loop over them.
"GEN7_" prefixes are more common than "_IVB" suffixes, so use that.
Gen6 only supports a single stream, so the single #define should be
fine. However, SO_NUM_PRIM_STORAGE_NEEDED was a poor name. For one,
the word "NUM" doesn't appear in the actual name of the register.
It's also confusingly generic, as it doesn't exist on Gen7+. Add a
"GEN6_" prefix for clarity.

Previously we would always find the 2D sub-surface of interest,
and then program the surface to this location. Now we always
program the 3DSTATE_DEPTH_BUFFER at the start of the surface.
To select the lod/slice, we utilize the lod & minimum array
element fields.
As part of this change, we must revert 1f112ccf:
Revert "i965/gen7: Align all depth miplevels to 8 in the X direction."
We also must disable brw_workaround_depthstencil_alignment for
gen >= 7. Now the hardware will handle alignment when rendering
to additional slices/LODs.

For gen >= 7, we will use the lod/minimum-array-element fields to
support layered rendering. This means that we must restrict
the depth & stencil attachments to match in various more retrictive
ways. (Now the width, height, depth, LOD and layer must match)
The reason width, height, and depth must match is that the hardware
has a single set of width, height, and depth settings (in
3DSTATE_DEPTH_BUFFER) that affect both the depth and stencil buffers.
Since these controls determine the miptree layout, they need to be
set correctly in order for lod and minimum-array-element to work
properly. So the only way rendering can work is if the width,
height, and depth match.
In the future, if this restriction proves to be a problem (say
because some crucial client application relies on rendering to
different levels/layers of stencil and depth buffers), then we can
always work around the restriction by copying depth and/or stencil
data to a temporary buffer prior to rendering (much in the same way
that brw_workaround_depthstencil_alignment() does today for
gen < 7), but hopefully that won't be necessary.

don't meet the size alignment requirements.

Geometry shader support in the Mesa front end is still fairly
preliminary. Many features are untested, and the following things are
known not to work:
- The gl_in interface block
- The gl_ClipDistance input
- Transform feedback of geometry shader outputs
- Constants that are new in GLSL 1.50 (e.g. gl_MaxGeometryInputComponents)
This isn't a problem, since no back-end drivers currently enable
geometry shaders. However, to make sure no one gets the wrong
impression, emit a nasty warning to let the user know that geometry
shader support isn't complete.

Previously, we assumed that the only way Mesa would expose geometry
shader support was via the ARB_geometry_shader4 extension. But this
extension has some extra complications over GL 3.2 (interactions with
compatibility-only features, and link-time initialization of the
constant gl_VerticesIn). So we want to allow for the possibility of
supporting GL 3.2 (with GLSL 1.50 style geometry shaders) even if
ctx->Extensions.ARB_geometry_shader4 is false.
This patch adds a new function, _mesa_has_geometry_shaders(), which
returns true if either ARB_geometry_shader4 is supported or the GL
version is at least 3.2 desktop. Since compute_version() only enables
GL 3.2 functionality when GLSL 1.50 support is present, a sufficient
way for a back-end to advertise geometry shader support is to set
ctx->Const.GLSLVersion >= 150.
v2: Remove unnecessary ctx->Const.GeometryShaders150 constant.
