glcpp: error on multiple #else/#elif directives
The preprocessor currently accepts multiple else/elif-groups per if-section. The GLSL-preprocessor is defined by the C++ specification, which defines the following parse-rule: if-section: if-group elif-groups(opt) else-group(opt) endif-line This clearly only allows a single else-group, that has to come after any elif-groups. So let's modify the code to follow the specification. Add test to prevent regressions.
