Zach BrownandMark Fasheh e354fd18b1 scoutfs: add sysfs.c, fsid file ...

I wanted to add a sysfs file that exports the fsid for the mount of a
given device.  But our use of sysfs was confusing and spread through
super.c and counters.c.

This moves the core of our sysfs use to sysfs.c.  Instead of defining
the per-mount dir as a kset we define it as an object with attributes
which gives us a place to add an fsid attribute.

counters still have their own whack of sysfs implementation.  We'll let
it keep it for now but we could move it into sysfs.c.  It's just counter
interation around the insane sysfs obj/attr/type nonsense.  For now it
just needs to know to add its counters dir as a child of the per-mount
dir instead of adding it to the kset.
