This patch adds MESA_SHADER_COMPUTE to the gl_shader_stage enum.
Also, where it is trivial to do so, it adds a compute shader case to
switch statements that switch based on the type of shader. This
avoids "unhandled switch case" compiler warnings.

This reduces confusion since gl_shader::Type is sometimes
GL_SHADER_PROGRAM_MESA but is more frequently
GL_SHADER_{VERTEX,GEOMETRY,FRAGMENT}. It also has the advantage that
when switching on gl_shader::Stage, the compiler will alert if one of
the possible enum types is unhandled. Finally, many functions in
src/glsl (especially those dealing with linking) already use
gl_shader_stage to represent pipeline stages; using gl_shader::Stage
in those functions avoids the need for a conversion.
Note: in the process I changed _mesa_write_shader_to_file() so that if
it encounters an unexpected shader stage, it will use a file suffix of
"????" rather than "geom".

Previously, we had an enum called gl_shader_type which represented
pipeline stages in the order they occur in the pipeline
(i.e. MESA_SHADER_VERTEX=0, MESA_SHADER_GEOMETRY=1, etc), and several
inconsistently named functions for converting between it and other
representations:
- _mesa_shader_type_to_string: gl_shader_type -> string
- _mesa_shader_type_to_index: GLenum (GL_*_SHADER) -> gl_shader_type
- _mesa_program_target_to_index: GLenum (GL_*_PROGRAM) -> gl_shader_type
- _mesa_shader_enum_to_string: GLenum (GL_*_{SHADER,PROGRAM}) -> string
This patch tries to clean things up so that we use more consistent
terminology: the enum is now called gl_shader_stage (to emphasize that
it is in the order of pipeline stages), and the conversion functions are:
- _mesa_shader_stage_to_string: gl_shader_stage -> string
- _mesa_shader_enum_to_shader_stage: GLenum (GL_*_SHADER) -> gl_shader_stage
- _mesa_program_enum_to_shader_stage: GLenum (GL_*_PROGRAM) -> gl_shader_stage
- _mesa_progshader_enum_to_string: GLenum (GL_*_{SHADER,PROGRAM}) -> string
In addition, MESA_SHADER_TYPES has been renamed to MESA_SHADER_STAGES,
for consistency with the new name for the enum.

Previously, _mesa_glsl_shader_target_name() had an overload for GLenum
and an overload for the gl_shader_type enum, each of which behaved
differently. However, since GLenum is a synonym for unsigned int, and
unsigned ints are often used in place of gl_shader_type (e.g. in loop
indices), there was a big risk of calling the wrong overload by
mistake. This patch gives the two overloads different names so that
it's always clear which one we mean to call.

This patch implements the common support code required for the
ARB_shader_atomic_counters extension. It defines the necessary data
structures for tracking atomic counter buffer objects (from now on
"ABOs") associated with some specific context or shader program, it
implements support for binding buffers to an ABO binding point and
querying the existing atomic counters and buffers declared by GLSL
shaders.
v2: Fix extension checks. Drop unused MAX_ATOMIC_BUFFERS constant.

The queries GEOMETRY_VERTICES_OUT, GEOMETRY_INPUT_TYPE, and
GEOMETRY_OUTPUT_TYPE (defined by GL 3.2) differ from the corresponding
queries in ARB_geometry_shader4 in the following ways:
- They use different enum values
- They can only be queried; they cannot be set.
- Attempting to query them yields INVALID_OPERATION if the program is
not linked, or lacks a geometry shader.
This patch switches us over from the ARB_geometry_shader4 behaviour to
the GL 3.2 behaviour.

Paused transform feedback objects may refer to a program other than the
current program. If any active objects refer to a program, LinkProgram
must reject the request to relink.
The code to detect this is ugly since _mesa_HashWalk is awkward to use,
but unfortunately we can't use hash_table_foreach since there's no way
to get at the underlying struct hash_table (and even then, we'd need to
handle locking somehow).
Fixes the last subcase of Piglit's new ARB_transform_feedback2
api-errors test.

This patch extracts the following logic from
validate_vertex_shader_executable():
(a) Generate an error if the shader writes to both gl_ClipDistance and
gl_ClipVertex.
(b) Record whether the shader writes to gl_ClipDistance in
gl_shader_program for use by the back-end.
(c) Record the size of gl_ClipDistance in gl_shader_program for use by
transform feedback logic.
And moves it into a function that is shared between vertex and
geometry shaders.
Strictly speaking we only need to have shared logic for (b) and (c)
right now (since (a) only matters in compatibility contexts, and we're
only implementing geometry shaders in core contexts right now). But
the three are closely related enough that it seems sensible to keep
them together.

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.

This patch creates a single function to copy the the UsesClipDistance

this logic was duplicated in the i965-specific function
brw_link_shader() and the core mesa function _mesa_ir_link_shader().
This logic will have to be expanded to support geometry shaders, and I
don't want to have to update it in two separate places.

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.

If the active uniform is an array, then the length of the uniform name should
include the three extra characters for the "[0]" suffix, which is required by
the GL 4.2 spec to be appended to the uniform name in glGetActiveUniform().
This avoids the situation where the output buffer does not have enough space
to hold the "[0]" suffix, resulting in an incomplete array specification like
"foobar[0".
NOTE: This is a candidate for the 9.1 branch.
