A new utility to test VFS system and modules

Just now it is acommandline tool like smbclient and rpcclient that is able to
perform operations on the file system passing through the vfs layer

It is not complete yet, some functions have simply faked up data, but module
loading works yet and basic operations too.

Thanks to Eric Lorimer for helping out with the initial setup.

Simo.
