Previously you could always glGetProgramiv one of the transform feedback
or geometry shader enums even if the extension wasn't supported.
In addtion, this reverts part of bda6ad27. I think the hunks involving
GL_PROGRAM_BINARY_LENGTH_OES were spurious. Mesa has no support for any
other part of GL_OES_get_program_binary.
v2: Remove redundant return in get_programiv based on review feedback
from Matt Turner.
v3: Correctly handle UBO related enums.
v4: Emit the bad enum in the _mesa_error call based on review feedback
from Brian Paul.

Calling glDeleteShader() should mark shaders as pending for deletion,
but shouldn't decrement the refcount every time. Otherwise, repeated
glDeleteShader() is not safe.
This is particularly bad since glDeleteProgram() frees shaders: if you
first call glDeleteShader() on the shaders attached to the program (thus
decrementing the refcount), then called glDeleteProgram(), it would try
to free them again (decrementing the refcount another time), causing
a refcount > 0 assertion to fail.
Similar to commit d950a778.
NOTE: This is a candidate for the 8.0 branch.

Rather than looking at the settings in individual assembly programs,
look at the settings in the top-level uniform values. The old code
was flawed because examining each shader stage in isolation could
allow inconsitent usage across stages (e.g., bind unit 0 to a
sampler2D in the vertex shader and sampler1DShadow in the fragment
shader).

Previously the fixed-function fragment shader was tracked as a
gl_program. This means that it shows up in the driver as a Mesa IR
program instead of as a GLSL IR program. If a driver doesn't generate
Mesa IR from the GLSL IR, that program is empty. If the program is
empty there is either no rendering or a GPU hang.

Switch all of the code in ir_to_mesa, st_glsl_to_tgsi, glUniform*,
glGetUniform, glGetUniformLocation, and glGetActiveUniforms to use the
gl_uniform_storage structures in the gl_shader_program.
A couple of notes:
* Like most rewrite-the-world patches, this should be reviewed by
applying the patch and examining the modified functions.
* This leaves a lot of dead code around in linker.cpp and
uniform_query.cpp. This will be deleted in the next patches.
v2: Update the comment block (previously a FINISHME) in _mesa_uniform

The gl_program_constants struct is for limits that are applicable to
any/all shader stages. Move the geometry shader-only fields into the
gl_constants struct.
Remove redundant MaxGeometryUniformComponents field too.
Need to flush rendering (or at least indicate that the rug might be getting
pulled out from underneath us) when a shader, buffer object or query object
is about to be deleted.
Also, this helps to tell the VBO module to unmap its current vertex buffer.
Directly include mtypes.h if a file uses a gl_context struct. This
allows future removal of headers that are not strictly necessary but
indirectly include mtypes.h for a file.
