Version 3.0 rc4

This is the fourth release candidate of testssl.sh 3.0 to reflect changes. All distributors and others who use it also for production-like environment are encouraged to switch to this branch as 2.9.5 won't be supported anymore once 3.0 has been released: Bug fixing will take place here only.

We take robustness seriously. This release contains bug fixes mostly.

For all changes, use git log.
