SHCreateStreamOnFileW is implemented in shlwapi, so we don't need
another implementation in shell32.

/*
|
|
||||||
* This class implements a pure IStream object
|
|
||||||
* and can be used for many purposes.
|
|
||||||
*
|
|
||||||
* The main reason for implementing this was
|
|
||||||
* a cleaner implementation of IShellLink which
|
|
||||||
* needs to be able to load lnks from an IStream
|
|
||||||
* interface so it was obvious to capsule the file
|
|
||||||
* access in an IStream to.
