OPTION). Add support for running bundled self-tests after building.
Do not run the self-tests by default, in order to be able to secure
portmgr's approval, but advise the user to do so before installing.
The self-tests will be turned on, when port-freeze is over.
Approved by: portmgr (pav)
and API stability.
The port does not build nor install the Perl and Tcl APIs -- these
will be added by separate ports.
