Add generic functions util_sysdir(); util_sysdir_path() and their special cases supplied for users: util_libdir(); util_libdir_path(); util_datadir(); util_datadir_path() The function util_sysdir() determines the absolute name of a s390-tools system directory. It could be data, or library directory. The function util_sysdir_path() determines the absolute name of a file installed in the s390-tools system directory. The function util_libdir() determines the absolute name of a s390-tools library directory. By default that name is defined by the compile-time macro TOOLS_LIBDIR (/lib/s390-tools). Users can specify an override by setting environment variable S390TOOLS_LIBDIR. The function util_libdir_path() determines the absolute name of a file installed in the s390-tools library directory. The function util_datadir() determines the absolute name of a s390-tools system data directory. By default the name is defined by the compile-time macro TOOLS_DATADIR (/usr/share/s390-tools/). Users can specify an override by setting environment variable S390TOOLS_DATADIR. The function util_datadir_path() determines the absolute name of a file installed in the s390-tools data directory. The ability to override the setting for TOOLS_LIBDIR and TOOLS_DATADIR is required for implementing tests on tools that are not installed in their default system path locations.
