jeff 990ca74cdc Eliminate kmem_arena and kmem_object in preparation for further NUMA commits. 
The arena argument to kmem_*() is now only used in an assert.  A follow-up
commit will remove the argument altogether before we freeze the API for the
next release.

This replaces the hard limit on kmem size with a soft limit imposed by UMA.  When
the soft limit is exceeded we periodically wakeup the UMA reclaim thread to
attempt to shrink KVA.  On 32bit architectures this should behave much more
gracefully as we exhaust KVA.  On 64bit the limits are likely never hit.
