Change the M_NAMEI allocations to use the zone allocator. This change

plus the previous changes to use the zone allocator decrease the useage
of malloc by half.  The Zone allocator will be upgradeable to be able
to use per CPU-pools, and has more intelligent usage of SPLs.  Additionally,
it has reasonable stats gathering capabilities, while making most calls
inline.
