Request: ASL2 (AMPL Solver Library for multiple threads and separate evaluation workspaces)

[cvanaret]

ASL (AMPL Solver Library, see #215) is available as a variant called solvers2 (tarball here, user manual here) that is particularly suited for multiple threads or to separate evaluation workspaces. It was recommended to me for the implementation of a trust-region SQP method within my solver Uno.
I'm hoping it shouldn't be too much work to build upon the recipe for ASL.

Hi @cvanaret, at minimum, this needs some input from @dpo.

Is there are diff of the two versions? Are they compatible, or does it require a massive change?

In the near-term, it seems like Bob suggests a way you can keep using the original ASL.

I wasn't aware that solver2 existed. Give me a little time to look around and get a feel for what's changed. If it hasn't changed too much, adapting the current interface shouldn't be too hard.

Thanks Dominique!
