Trie: Fix trie format
After switching to 16-way tries, trie format ignored unaligned / internal prefixes and only reported the primary prefix of a trie node. Fix trie format by showing internal prefixes based on the 'local' bitmask of a node. Also do basic (intra-node) reconstruction of prefix patterns by finding common subtrees in 'local' bitmask. In future, we could improve that by doing inter-node reconstruction, so prefixes entered as one pattern for a subtree (e.g. 192.168.0.0/18+) would be reported as such, like with aligned prefixes.
