Change APIs

Change fields of tokens, results of lexical analysis, as follows:
- Rename: mode -> mode_id
- Rename: kind_id -> mode_kind_id
- Add: kind_id

The kind ID is unique across all modes, but the mode kind ID is unique only within a mode.

Change fields of a transition table as follows:
- Rename: initial_mode -> initial_mode_id
- Rename: modes -> mode_names
- Rename: kinds -> kind_names
- Rename: specs[].kinds -> specs[].kind_names
- Rename: specs[].dfa.initial_state -> specs[].dfa.initial_state_id

Change public types defined in the spec package as follows:
- Rename: LexModeNum -> LexModeID
- Rename: LexKind -> LexKindName
- Add: LexKindID
- Add: StateID
