Conf: Allow keywords to be redefined by user symbols
Most syntactic constructs in BIRD configuration (e.g. protocol options) are defined as keywords, which are distinct from symbols (user-defined names for protocols, variables, ...). That may cause backwards compatibility issue when a new feature is added, as it may collide with existing user names. We can allow keywords to be shadowed by symbols in almost all cases to avoid this issue. This replaces the previous mechanism, where shadowable symbols have to be explictly added to kw_syms.
