I started on a journey that I unfortunately never got around to finish, with using the license-unencumbered capstone hsdis implementation, and include that as default when building the JVM.

Apparently there is still need for the binutils hsdis, which I guess is due to limitations in the capstone version compared to binutils. (?) Otherwise binutils is just a plain pain to work with from the JDK perspective, due to the incompatible license involved.

Given that the capstone hsdis version can be made to match the binutil version in functionality, I think it would be a much saner path forward to focus on that implementation, and just bundle it with the JVM.
