Patchset

.NET CoreRT performs thread tear down in a FLS callback which is currently not
called in Wine. If the tear down callback is not performed on thread
termination, the application later crashes on accessing the data from already
freed static TLS data storage area.

The attached patchset is fixing the issue.
