malloc_conf does not reliably work with MSVC, which complains of "inconsistent dll linkage", i.e. its inability to support the application overriding malloc_conf when dynamically linking/loading. Work around this limitation by adding test harness support for per test shell script sourcing, and converting all tests to use MALLOC_CONF instead of malloc_conf.
