MTRIE Optimisations 2
1) 16-8-8 stride. Reduce trie depth walk traded with increased memory in the top PLY. 2) separate the vector of protocol-independent (PI) fib_table_t with the vector of protocol dependent (PD) FIBs. PD FIBs are large structures, we don't want to burn the memory for ech PD type 3) Go straight to the PD FIB in the data-path thus avoiding an indirection through, e.g., a PLY pool.
