[PATCH 3/7] style: src: remove useless reference to 'int' in integral types

[Akim Demaille]

* src/AnnotationList.c, src/AnnotationList.h, src/InadequacyList.h,
* src/closure.c, src/closure.h, src/gram.c, src/gram.h, src/ielr.c,
* src/location.c, src/output.c, src/reader.c, src/relation.c,
* src/scan-code.l, src/scan-gram.l, src/tables.c, src/tables.h:
Prefer 'unsigned' to 'unsigned int'.  Likewise for long and short.
