Merge branch 'fib_trie_next'

====================
Fixes and improvements for recent fib_trie updates

While performing testing and prepping the next round of patches I found a
few minor issues and improvements that could be made.

These changes should help to reduce the overall code size and improve the
performance slighlty as I noticed a 20ns or so improvement in my worst-case
testing which will likely only result in a 1ns difference with a standard
sized trie.
