This package is the utils package but with all the python-only code
removed from it. What remains is the C++ code and the pybind11
interfaces to that code.

This makes it possible for C++ applications that previously used
the utils C++ code to still use it without modification. Changing
to lsst::cpputils requires all the code to change because of the
complexity of forwarding namespaces from the utils package to
the cpputils package through a deprecation period.

This reverts commit aae2ac6.

This allows legacy code to still look for lsst::utils
A symlink is used per file. This makes it explicit which
include files are supporting deprecation.

Also, directory symlinks are not currently supported
by sconsUtils install.

Has not been used for 3 years since DM-10384.
