Correction to: Record which promise set each variable.

Our current Promise may be a copy, that'll be free()d at the end of
the current convergence pass; comparing this to the Promise of a later
assignment won't be equal even if it's the original (or another copy
of it); and dereferencing it during reporting shall be regrettable.
Fortunately, a Promise's .org_pp records the original in any copies,
so we can record that instead, bypassing both problems.

To record the caused of failure in generated xml
Make sure printing of variables and classes is off by default.
Make testall test what's in the current folder, not `dirname $0`.

This is so that it can be called directly from masterfiles.
Export variables to tests so we can find the enterprise plugin.
