Explicit header definitions for Open XL warnings

Open XL 2.1 on z/OS reports some of the implicit declarations as errors, and requires these to be explicitly defined. Most of the underlying changes are to address this concern and some other fixes pertaining to compilation errors. _EXT is defined in port/zos390/omrosdump.c as the cnap() function declaration within the ctype.h header is guarded behind the _EXT macro and required to be present for Open XL.
