[IPV4]: fib_trie root node settings
The threshold for root node can be more aggressive set to get better tree compression. The new setting mekes the root grow from 16 to 19 bits and substansial improvemnt in Aver depth this with the current table of 214393 prefixes But really the dynamic resize should need more investigation both in terms convergence and performance and maybe it should be possible to change... Maybe just for the brave to start with or we may have to back this out.
