"make test" redux

[Dan Kegel]

We've had a test suite for six or so years now, and we keep
getting closer to having it pass reliably, but we're still not quite there.
I see from http://test.winehq.org that fifteen tests fail on at
least one machine.

There are several bugs that only cause make test to fail if
you run them with WINEDEBUG=warn+heap, but those seem
just as important to me.

On my own machine, here are the bugs related to make test failures:
http://bugs.winehq.org/show_bug.cgi?id=12925
http://bugs.winehq.org/show_bug.cgi?id=14078
http://bugs.winehq.org/show_bug.cgi?id=17414
http://bugs.winehq.org/show_bug.cgi?id=17518
http://bugs.winehq.org/show_bug.cgi?id=19183

I submitted a patch to fix http://bugs.winehq.org/show_bug.cgi?id=17518
but it'd be nice to get some love on the others.
