[patch] 3.2 test - add fsctl_recall_offline support

[Alexander Bokovoy]

David, thanks for the patches.

I'm just back from the red-sea-without-network family trip and
catching up with lots of mail. Expect review in a week or so -- I saw
comments from Jeremy and James already.

>  Patches in apply order:
>
>  add_recall_offline_vfs_func.patch
>  =================================
>     Add new RECALL_OFFLINE vfs function
>
>     To be used for recalling files migrated to offline storage by a Hierarchical
>     Storage Management system.
>
>  support_setupcount_nttrans.patch
>  ================================
>     Support Setup[SetupCount] values in nttrans response packets
>
>     send_nt_replies currently sets SetupCount to zero, however some packets
>     require different values. When testing FSCTL_RECALL_FILE, Windows XPsp2
>     was observed dropping connections where SetupCount was not one in the server
>     response.
>
>     The SNIA CIFS documentation also describes NT_TRANSACT_IOCTL server response
>     packets as having a SetupCount of 1.
>
>  add_fsctl_recall_file_support.patch
>  ===================================
>     FSCTL_RECALL_FILE can be used to recall files moved offline by hierarchical
>     storage management software.
>
>     The nttrans ioctl packet is handled in the following steps:
>     - check for FILE_SUPPORTS_REMOTE_STORAGE, if without, return error
>     - return error if attempting to recall a directory.
>     - if SMB_VFS_IS_OFFLINE() is false return success immediately
>     - otherwise, call SMB_VFS_RECALL_OFFLINE() to recall the file
