[PATCH v2 0/3] MR4073: msxml3: Stop possible typelib out of bounds access (Coverity)

[Alistair Leslie-Hughes (＠alesliehughes)]

typelib has an array size of 2 (eg LibXml_Last), so a lookup
of IID_NULL will result in a lookup of the third index.

  v2: msxml3: Free IBindCtx on error paths (Coverity)
      msxml3: Move tid_NULL out of possible enum values.
      msxml3: Dont call qsort if we have no data (Coverity).
