  Log:
  * Add a "how" argument to uma_zone constructors and initialization functions
    so that they know whether the allocation is supposed to be able to sleep
    or not.
  * Allow uma_zone constructors and initialation functions to return either
    success or error.  Almost all of the ones in the tree currently return
    success unconditionally, but mbuf is a notable exception: the packet
    zone constructor wants to be able to fail if it cannot suballocate an
    mbuf cluster, and the mbuf allocators want to be able to fail in general
    in a MAC kernel if the MAC mbuf initializer fails.  This fixes the
    panics people are seeing when they run out of memory for mbuf clusters.
  * Allow debug.nosleepwithlocks on WITNESS to be disabled, without changing
    the default.
  
  Both bmilekic and jeff have reviewed the changes made to make failable
  zone allocations work.
