os400: fix various ILE/RPG types definitions. Adjust build scripts. - A typo caused an undefined symbol reference. - A structure field name did not match the corresponding C name due to a typo. - Some structured fields were not properly aligned. - The long/ulong types were wrongly mapped to 64-bit types. - A typo in a /include directive caused a compilation error. - Doc files copy now converts from UTF-8 and split long lines. - Adjust /include file name mapping translation for proper prefix handling.
