Initial import of ongoing mbuf work
 - Introduce a m_size field to simplify a great number of macros and
   consumer code.  Paves the way for more flexible mbuf sizes once
   the field is honored in all code.
 - Streamline mbuf allocation/free code.  Move things into functions
   that should not be inlined and functions to inlines when the
   calling footprint exceeds the function text size.
 - Reference count mbufs rather than clusters.  All mbufs have a ref
   so uma refcnt zones and the super expensive uma_find_refcnt() is
   not necessary.  Don't duplicate m_ext areas, call m_refm() to
   reference a specific data area of a target mbuf.
 - Retire UMA refcnt zones.  These were too inefficient to be useful.
