[Coin-ipopt] Ipopt C++ version

Hi Kirk,

Yes, we will maintain a C and Fortran interface, so that name mangling
should not be an issue.  There should not be a problem to hook up Ipopt
from Java through the C interface.

We will probably look for alpha/beta testers for the new version at some
point - so be warned :-)  We hope that the new design/core will be easier
to understand and hope that it will allow others to contribute to the
code.

Greetings,

Andreas
