- Split the cached and resident pages tree into 2 distinct ones.
This makes the RED/BLACK support go away and simplifies a lot vmradix
functions used here. This happens because with patricia trie support
the trie will be little enough that keeping 2 diffetnt will be
efficient too.
- Reduce differences with head, in places like backing scan where the
optimizazions used shuffled the code a little bit around.
