Refactor contigmalloc() into two functions: a simple front-end that deals

with the malloc tag and calls a new back-end, kmem_alloc_contig(), that
allocates the pages and maps them.

The motivations for this change are two-fold: (1) A cache mode parameter
will be added to kmem_alloc_contig().  In other words, kmem_alloc_contig()
will be extended to support the allocation of memory with caller-specified
caching. (2) The UMA allocation function that is used by the two jumbo
frames zones can use kmem_alloc_contig() in place of contigmalloc() and
thereby avoid having free jumbo frames held by the zone counted as live
malloc()ed memory.
