Added support for FADF_HAVEIID, FADF_RECORD, FADF_HAVEVARTYPE.
Implemented SafeArrayAllocDescriptorEx and SafeArrayGetVarType
correctly.
Fixed second argument of SafeArrayCopyData (it is just SAFEARRAY*).
Changed allocation to include 16 bytes before the SAFEARRAY (to store
IID/VARTYPE/IRecordInfo*).
VARTYPE -> size array was not indexed correctly.
Added lots of testcases for most functionality.
Added IRecordInfo interface definition.
