Bring DOCSIS Mac Management "dissectors" into modernity.
1. Use proto_tree_add_item_ret_uint to remove separate "gets"
2. Remove if (tree)s that prevented expert_info
3. Apply consistent whitespace
4. Apply consistent TLV behavior, making T and L always filterable
5. Remove T name (of TLV) from field name itself (where applicable)
6. Use BASE_UNIT_STRING and BASE_NO_DISPLAY_VALUE
