CDE has relied upon catgets() implementations following a relaxed interpretation of the XPG internationalization standard that ignored -1, the standard error value returned by catopen, as the catalog argument. However, this same behavior causes segmentation faults with the musl C library. This patch: - Centralizes (with the exception of ToolTalk) all calls to catopen(), catgets(), and catclose() through MsgCat within the DtSvc library. - Prevents calls to catgets() and catclose() that rely upon undefined behavior. - Eliminates a number of bespoke catgets() wrappers, including multiple redundant caching implementations designed to work around a design peculiarity in HP/UX. - Eases building CDE without XPG internationalization support by providing the appropriate macros.
