Relates to #198. Now, we create a delegate method body which basically
looks as follows:

public void methodOne() {
  if (this.ajc$instance$MyAspect$MyMixin == null) {
    synchronized(this) {
      if (this.ajc$instance$MyAspect$MyMixin == null) {
        this.ajc$instance$MyAspect$MyMixin = MyAspect.aspectOf().createImplementation(this);
      }
    }
  }
  this.ajc$instance$MyAspect$MyMixin.methodOne();
}

The idea for the outer null check is from @aclement, see
https://github.com/eclipse/org.aspectj/pull/205#issuecomment-1371556080.

previous commit now passes.

StringBuffer is a legacy synchronized class. StringBuilder is a direct replacement to StringBuffer which generally have better performance.

This was required by the Eclipse team as one precondition for the next
release.

In this version unless you specify an aspect is privileged then the
pertypewithin clause will not match types not visible from the aspect
(private types or default vis types in another package)

Debating whether to change this to not require privileged.

Added 1.7.3 test suite
