In desktop GLSL, location qualifiers are case-insensitive. In GLSL
ES, they are case-sensitive. This patch handles the difference by
using a new function to match layout qualifiers,
match_layout_qualifier(), which calls either strcmp() or strcasecmp()
as appropriate.
Fixes piglit tests:
- layout-not-case-sensitive-in.geom
- layout-not-case-sensitive-max-vert.geom
- layout-not-case-sensitive-out.geom
- layout-not-case-sensitive.frag
