Converted strcasecmp to sqlite3StrICmp. Test code only. (CVS 5654) (check-in: bdeefe37 user: shane tags: trunk)

Modify the aBuiltinFunc array in func.c to use the WSD macros. (CVS 5653) (check-in: 846fff5f user: danielk1977 tags: trunk)
18:34
Begin adding support for the SQLITE_OMIT_WSD macro. Some (many) WSD variables still need wrappers added to them. (CVS 5652) (check-in: 573d92ab user: danielk1977 tags: trunk)
