[Piglit] [PATCH] Make piglitutil library API-independent

[Blaž Tomažič]

Currently all utility libraries (piglitutil, piglitutil_gles1,
piglitutil_gles2) have built-in the same API-independent code and the
code from piglit-util.{c,h} contains OpenGL functionality. To share more
code across different APIs (e.g. OpenCL, OpenGL) this code should be
split. piglit-util.{c,h} and piglitutil library should be
API-independent.


      * Commits 1 and 2:
        OpenGL-dependent code from piglit-util.{c,h} is moved to
        piglit-util-gl-common.{c,h} (All includes from other files are
        properly renamed).
        File piglit-util-enum.c is renamed to piglit-util-gl-enum.c for
        the same purpose, because it contains enums from OpenGL.
        
      * Commit 3:
        The function for reading files from shader-load.c is moved to
        piglit-util.c, because it doesn't depend on any API or shaders
        (as its name wrongly suggests). In the process shader-load.c is
        deleted because it contains no other code.
        
      * Commits 4 and 5:
        The piglitutil library is split to utility library for OpenGL
        (piglitutil_gl) and API-independent utility library
        (piglitutil). All other utility libraries are now linked to
        piglitutil and all OpenGL test executables to piglitutil_gl.
