Add a system call to allow filesystem information to be queried.  A request
value can be given to indicate the desired attribute.  Support is provided
for enumerating multi-value attributes.

Has anyone seriously reviewed this?  It might make sense to defer this
to a followup patch set.  Also:

params->request indicates the attribute/attributes to be queried.  This can
be one of:

        fsinfo_attr_statfs              - statfs-style info
        fsinfo_attr_fsinfo              - Information about fsinfo()

Constants are almost always all caps.  Is there any reason these are lowercase?
