[PATCH v3 0/9] MR7286: dlls/oleaut32: Vastly cleanup and make consistent fnIsName() and fnFindName()

[Edward OC (＠funfunctor)]

Make both method calls;

1. Consistently written with parameter names as per spec.
2. Fix parameter validation to be consistent with spec.
3. Fix szNameBuf parameter semantics as per spec.
4. Fix szNameBuf casing str search as per spec.
5. Factor out common code into TLB_ helpers vastly improves readability.
