[PATCH] [CIFS] Allow setting per-file compression via SMB3

[Stefan (metze) Metzmacher]

Hi Steve,

Why is this SMB3 specific?

> Windows users often set the compressed flag (it can be
> done from the desktop and file manager).  David Disseldorp

> presumably would be easy to set too via SMB3)

It seems there're some unrelated changes in the commit,
wouldn't it be better to split this into 2 or 3 commits?
