and temps that we can support.

constants and read them with "Read" messages/instructions.  When only a
small number of constants are used, we can still use the old method.

The code works for fragment shaders only (and is actually disabled) for now.

code-gen to fetch the constants which are referenced by the shader
instructions.

glsl: implement compiling/linking of separate compilation units

A shader program may consist of multiple shaders (source code units).
If we find there are unresolved functions after compiling the unit that
defines main(), we'll concatenate all the respective vertex or fragment
shaders then recompile.

This isn't foolproof but should work in most cases.

mesa: fix a recursive display list problem

This fixes an issue when compiling glCallList() into another display list
when the mode is GL_COMPILE_AND_EXECUTE.

Before, the call to glCallList() called _mesa_save_CallList() which called
neutral_CallList() which then called _mesa_save_CallList() again.  In the
end, the parent display list contained two calls to the child display list
instead of one.

Let's be on the lookout for regressions caused by this change for a while
before we cherry-pick this elsewhere.
