Code Issues Releases Activity

Define four constants, MBUF_{,MEM,CLUSTER,PACKET,TAG}_MEM_NAME, which

are string names for their respective UMA zones and malloc types, and
are passed into uma_zcreate() and MALLOC_DEFINE().  Export them
outside of _KERNEL in mbuf.h so that netstat can reference them.

Change the names to improve consistency, with each zone/type
associated with the mbuf allocator being prefixed mbuf_.
