glGetUniformIndices requires that the block instance index not be
present in the name of queried uniforms. However,
gl_uniform_buffer_variable::Name will include the instance index. The
IndexName field is added to handle this difference.
Note that currently IndexName will always point to the same string as
Name. This will change soon.

Not all float32 values can be exactly represented as a float16.
_mesa_float_to_half() rounded such intermediate float32 values to zero by
truncating unrepresentable bits in the mantissa.
This patch improves _mesa_float_to_half() by rounding intermediate float32
values to the nearest float16; when the float32 is exactly between two
float16 values we round to the one with an even mantissa. This behavior is
preferred over the old behavior because:
- It has reduced bias relative to the old behavior.
- It reproduces the behavior of real hardware: opcode F32TO16 in
Intel's GPU ISA.
- By reproducing the behavior of the GPU (at least on Intel hardware),
compile-time evaluation of constant packHalf2x16 GLSL expressions will
result in the same value as if the expression were executed on the GPU.

Move round_to_even's definition to mesa/main so that _mesa_float_to_half()
can use it in order to eliminate rounding bias.
In additon to moving the fuction definition, prefix its name with "_mesa",
just as all other functions in mesa/main are prefixed.

This patch replaces the three ir_variable_mode enums:
- ir_var_in
- ir_var_out
- ir_var_inout
with the following five:
- ir_var_shader_in
- ir_var_shader_out
- ir_var_function_in
- ir_var_function_out
- ir_var_function_inout
This eliminates a frustrating ambiguity: it used to be impossible to
tell whether an ir_var_{in,out} variable was a shader in/out or a
function in/out without seeing where the variable was declared in the
IR. This complicated some optimization and lowering passes, and would
have become a problem for implementing varying structs.
In the lisp-style serialization of GLSL IR to strings performed by
ir_print_visitor.cpp and ir_reader.cpp, I've retained the names "in",
"out", and "inout" for function parameters, to avoid introducing code
churn to the src/glsl/builtins/ir/ directory.
Note: a couple of comments in the code seemed to indicate that we were
planning for a possible future in which geometry shaders could have
shader-scope inout variables. Our GLSL grammar rejects shader-scope
inout variables, and I've been unable to find any evidence in the GLSL
standards documents (or extensions) that this will ever be allowed, so
I've eliminated these comments.

For non-generic compressed format we assert two things:
1. The format has already been validated against the set of available
extensions.
2. The driver only enables the extension if it supports all of the
formats that are part of that extension.

When performing a ReadPixels operation, we may be reading from a buffer that
stores alpha values, but that is actually representing a buffer with no alpha
channel. In this case, while rebasing the values, touch up all alpha values
read to 1.0.
This commit fixes the following piglit (sub) tests:
ARB_texture_float/fbo-colormask-formats
GL_RBG16F_ARB
EXT_texture_snorm/fbo-colormask-formats
GL_RGB16_SNORM
GL_RGB8_SNORM
GL_RGB_SNORM
It likely improves the results of other tests as well, but a PASS remains
elusive due to additional bugs.

These were introduced in 2000 during a rework of the TNL module (commit
cab974cf6c2dbfbf5dd5d291e1aae0f8eeb34290), though I'm having a hard time
finding an instance there of one of these Exec functions being changed
at runtime.
Regardless, as far as I can tell now, these functions don't get changed,
by grepping for calls to SET_* to change the dispatch table (we do change
functions in GLvertexformat at runtime, but those don't overlap with
this set of functions). Remove them and just let them be initialized to
the same functions as are in the Exec table.
