[PATCH v3 0/6] MR6640: propsys: Support converting to BSTR for PropVariantToVariant.
This is based on top of !6526, will mark ready after !6526 is merged. -- v3: propsys: Support converting to BSTR for PropVariantToVariant. propsys: Use debugstr_variant for the trace in VariantToPropVariant. propsys: Implement PropVariantToBSTR. propsys/tests: Test truncating for PropVariantToString. propsys/tests: Test PropVariantToBSTR. propsys: Add PropVariantToBSTR stub. https://gitlab.winehq.org/wine/wine/-/merge_requests/6640

Hi, It looks like your patch introduced the new failures shown below. Please investigate and fix them before resubmitting your patch. If they are not new, fixing them anyway would help a lot. Otherwise please ask for the known failures list to be updated. The tests also ran into some preexisting test failures. If you know how to fix them that would be helpful.

The problem here is that WCHAR* and BSTR are potentially different, BSTR can support embedded nulls. What should happen if you have VT_BSTR propvar as input? I add a test in V2:
``` WCHAR *bstr, test_bstr[] = {'a', 0, 'b', 0, 'c'}; ...
