82291f64e3 mesa: Add functions for doing unlocked hash table lookups
This patch adds functions for locking/unlocking the mutex, along with
_mesa_HashLookupLocked() and _mesa_HashInsertLocked()
that do lookups and insertions without locking the mutex.

These functions will be used by the ARB_multi_bind entry points to
avoid locking/unlocking the mutex for each binding point.

eb502c31a0 i965: Fix format of private renderbuffers
intel_alloc_renderbuffer_storage() will clobber rb->Format which was
already set up by intel_create_renderbuffer(). This causes the driver
to potentially create the depth buffer in the wrong format.

In practice this makes the depth buffer Z24 even if the visual has
depthBits==16.

The incorrect depth buffer format doesn't seem to cause any actual
problems in i965, but it seems like we should fix it anyway. I see
Z16 has been more or less deprecated in the driver except the for
the depthBits==16 case. But if we want to use Z24 even in that
case (not sure it's really legal?) it would look better if the
code made that decision explicitly rather than relying on the
format to get magically overwritten by the renderbuffer code.

d3edc31810 i915: Fix format of private renderbuffers
intel_alloc_renderbuffer_storage() will clobber rb->Format which was
already set up by intel_create_renderbuffer(). This causes the driver
to potentially create the depth buffer in the wrong format.

Long time ago things worked by accident because
_mesa_choose_tex_format() checked for ARB_depth_texture
and thus returned MESA_FORMAT_NONE on gen2 hardware. Somehow
that ended up working when depthBits==16 because the driver
would then pick DEPTH_FRMT_16_FIXED. Not sure how, but things
also seemed to work with depthBits==24.

Things started to go more sideways at:
 commit 6ae473221a
 Author: Eric Anholt <eric@anholt.net>
 Date:   Mon Apr 22 16:04:25 2013 -0700

    intel: Fold the one last function intel_tex_format.c into the caller.

since that caused intel_miptree_create_layout() to divide by zero
when encoutering MESA_FORMAT_NONE (bw==0). So after this
commit things were broken enough that many applications wouldn't even
run.

Things got a bit better at:
 commit c245efe7e8
 Author: Eric Anholt <eric@anholt.net>
 Date:   Thu Mar 21 09:50:45 2013 -0700

    mesa: Remove extension checking from ChooseTexFormat.

since now _mesa_choose_tex_format() would return MESA_FORMAT_X8_Z24
for GL_DEPTH_COMPONENT due to i915 erroneosly claiming that
MESA_FORMAT_X8_S24 (and others) are supported texture formats even
on gen2 hardware. So now the the div-by-zero was gone, but now the
driver would pick DEPTH_FRMT_24_FIXED_8_OTHER even when
depthBits==16 which caused rendering problems.

If we prevent rb->Format from getting clobbered for the depth buffer
things work much better. This makes the spinning title text visible
again in chromium-bsu at 16bpp, for example.

dc75479b7a mesa: Fix querying location of nth element of an array variable
This patch makes changes to the behavior of glGetAttribLocation(),
glGetFragDataLocation() and glGetFragDataIndex() functions.

Code changes handle a case described in following example:

shader program:
layout(location = 1)in vec4[4] a;
void main()
{
}

Currently, glGetAttribLocation("a") returns 1.
glGetAttribLocation("a[i]"), where i = {0, 1, 2, 3}, returns -1.
But the expected locations for array elements are: 1, 2, 3 and 4
respectively.

This clarification came up with the addition of
ARB_program_interface_query to OpenGL 4.3.

From Page 326 (page 347 of the PDF) of OpenGL 4.3 spec:
   "Otherwise, the command is equivalent to

    GetProgramResourceLocation(program, PROGRAM_INPUT, name);"

And, From Page 101 (page 122 of the PDF) of OpenGL 4.3 spec:

   "A string provided to GetProgramResourceLocation or
    GetProgramResourceLocationIndex is considered to match an active
    variable if

    • the string exactly matches the name of the active variable;
    • if the string identifies the base name of an active array, where
      the string would exactly match the name of the variable if the
      suffix "[0]" were appended to the string; or
    • if the string identifies an active element of the array, where
      the string ends with the concatenation of the "[" character, an
      integer (with no "+" sign, extra leading zeroes, or whitespace)
      identifying an array element, and the "]" character, the integer
      is less than the number of active elements of the array variable,
      and where the string would exactly match the enumerated name of
      the array if the decimal integer were replaced with zero."

V2: Simplify get_matching_index() function.
    Add relevant text from OpenGL spec in commit message.

Fixes failures in Khronos OpenGL CTS tests:
explicit_attrib_location_room
draw_instanced_max_vertex_attribs

Proprietary linux drivers of NVIDIA (331.49) matches the behavior
expected by OpenGL 4.3 spec.

8c61b6a99b glsl: Allow overlapping locations for vertex input attributes
Currently overlapping locations of input variables are not allowed for all
the shader types in OpenGL and OpenGL ES.

From OpenGL ES 3.0 spec, page 56:
   "Binding more than one attribute name to the same location is referred
    to as aliasing, and is not permitted in OpenGL ES Shading Language
    3.00 vertex shaders. LinkProgram will fail when this condition exists.
    However, aliasing is possible in OpenGL ES Shading Language 1.00 vertex
    shaders."

Taking in to account what different versions of OpenGL and OpenGL ES specs
say about aliasing:
   - It is allowed only on vertex shader input attributes in OpenGL (2.0 and
     above) and OpenGL ES 2.0.
   - It is explictly disallowed in OpenGL ES 3.0.

Fixes Khronos CTS failing test:
explicit_attrib_location_vertex_input_aliased.test
See more details about this at below mentioned khronos bug.

V2: Fix the case where location exceeds the maximum allowed attribute
    location.
V3: Simplify the condition added in V2.

64d6460a56 gallivm: fix 2 leaks in disassembly code
don't leak the MCSubtargetInfo (not really big, was already fixed with
llvm master) and TargetMachine (big). While this is only used for debugging
the leak is large enough to get you into trouble in some cases.
Tested with llvm 3.1 and master.
Before (llvm 3.1), GALLIVM_DEBUG=asm glxgears:
