cln::cl_foo::operator new(size_t, cl_foo*) to
cln::cl_foo::operator new(size_t, void*) so one can declare
std::vector<cln::cl_foo>, std::list<cln::cl_foo> etc. for
certain STL implementations (like libstdc++-v3).
I am too lazy for a detailed discussion of all the changes.
Many identifiers got their `cl_' stripped off. Ok, this is a
clumpsy CVS log-entry. Promise: more will soon go into the
file ChangeLog. I apologize for the inconvenience. :-(
