Final part of the slab updates:

Improve readability of /proc/slabinfo by adding a header, and add 
per-cpu statistics.
As a sideeffect, the "2.0" file format helps to mitigate the 2 vs 3 
parameter problem created by the previous patch: A script can check the 
file format version, and use 2 parameter for 1.x, three parameters for 2.x

Patch against 2.5.69-mm6, applies to 2.5.69-bk12 with some offsets.
