Eduard Shishkin a645ec0fc0 libutil: make TOOLS_LIBDIR and TOOLS_DATADIR configurable
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.
