[PATCH] FSRVP client support

[David Disseldorp]

Hi,

The following patch set adds support for the File Server Remote VSS
Protocl (MS-FSRVP) to rpcclient.

FSRVP support is new to Windows Server "8" Beta, and allows an SMB
client to request the creation and exposure of a share shadow-copy
(snapshot) via a dcerpc request to the FssagentRpc named pipe.
Windows Server "8" Beta FSRVP setup instructions are briefly documented
on on page 19 of:

Once the server is configured, rpcclient can be used as follows:

ddiss at plati:~> bin/rpcclient -k -U 'DOM\administrator%pw' ncacn_np:lutze[sign]

rpcclient $> fss_create_expose backup ro hyper

A number of smbtorture tests are also added, in preparation for FSRVP
server support.

"pidl: remove alignment pull at ParseStructPullPrimitives tail" is
included as a workaround for NDR64 dcerpc_bind_ack unmarshalling
problems, it is likely incorrect.

Feedback welcome.

Cheers, David
