Instead of `restriction` class methods, use the new free functions. Specific replacement actions are listed below. Note that class `restrictions` (plural) remains intact -- both its methods and its type hierarchy remain intact for now. Ensure full test coverage of the replacement code with new file test/boost/restrictions_test.cc and some extra testcases in test/cql/*. Drop some existing tests because they codify buggy behaviour (reference #6369, #6382). Drop others because they forbid relation combinations that are now allowed (eg, mixing equality and inequality, comparing to NULL, etc.). Here are some specific categories of what was replaced: - restriction::is_foo predicates are replaced by using the free function find_if; sometimes it is used transitively (see, eg, has_slice) - restriction::is_multi_column is replaced by dynamic casts (recall that the `restrictions` class hierarchy still exists) - utility methods is_satisfied_by, is_supported_by, to_string, and uses_function are replaced by eponymous free functions; note that restrictions::uses_function still exists - restriction::apply_to is replaced by free function replace_column_def - when checking infinite_bound_range_deletions, the has_bound is replaced by local free function bounded_ck - restriction::bounds and restriction::value are replaced by the more general free function possible_lhs_values - using free functions allows us to simplify the multi_column_restriction and token_restriction hierarchies; their methods merge_with and uses_function became identical in all subclasses, so they were moved to the base class - single_column_primary_key_restrictions<clustering_key>::needs_filtering was changed to reuse num_prefix_columns_that_need_not_be_filtered, which uses free functions Fixes #5799. Fixes #6369. Fixes #6371. Fixes #6372. Fixes #6382. Signed-off-by: Dejan Mircevski <dejan@scylladb.com>
