Previously we would fail in some parts of the code if we did not have a
premade configuration, now we use any code that was marked as Linux, BSD and
Solaris as our basis in order to support building unknown Unix systems.
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.
