*L10NFILE_LIST denotes a pool of lookup results of locale dependent
files of the same kind, sorted in decreasing order of ->filename.
DIRLIST and DIRLIST_LEN are an argz list of directories in which to
look, containing at least one directory (i.e. DIRLIST_LEN > 0).
MASK, LANGUAGE, TERRITORY, CODESET, NORMALIZED_CODESET, MODIFIER
are the pieces of the locale name, as produced by _nl_explode_name().
FILENAME is the filename suffix.
The return value is the lookup result, either found in *L10NFILE_LIST,
or - if DO_ALLOCATE is nonzero - freshly allocated, or possibly NULL.
If the return value is non-NULL, it is added to *L10NFILE_LIST, and
its ->next field denotes the chaining inside *L10NFILE_LIST, and
furthermore its ->successor[] field contains a list of other lookup
results from which this lookup result inherits. */
