testrunner 1: Turn into a package

Testrunner is a medium-large module that has a number of
different purposes. Since we want to improve the testing logic,
it is better to clean the module up before adding even more
code.
For compatibitity, the testrunner module will stay in place,
but redirect everything into the new "testing" package.

+Note the field "mod_name". I had split this before, but it is necessary
