This is a simplification of the getvalues(2) prototype and moving it to the
getxattr(2) interface, as suggested by Dave.

The patch itself just adds the possibility to retrieve a single line of
/proc/$$/mountinfo (which was the basic requirement from which the fsinfo
patchset grew out of).

But this should be able to serve Amir's per-sb iostats, as well as a host of
other cases where some statistic needs to be retrieved from some object.  Note:
a filesystem object often represents other kinds of objects (such as processes
in /proc) so this is not limited to fs attributes.

This also opens up the interface to setting attributes via setxattr(2).
