Check in an intial implementation of radix tree implementation to replace
the vm object pages splay.

TODO:
- Handle differently the negative keys for having smaller depth
  index nodes (negative keys caming from indirect blocks)
- Fix the get_node() by having support for a low reserved objects
  directly from UMA
- Implement the lookup_le and re-enable VM_NRESERVELEVEL = 1
- Try to rework the superpage splay of idle pages and the cache splay
  for every vm object in order to regain space on vm_page structure
- Verify performance and improve them (likely by having consumers to deal
  with several ranges of pages manually?)
