37ebe521e3 cql3/restrictions: Use free functions instead of methods
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.

511ae023f0 lwt: add lightweight transactions unit tests
These unit tests cover all CQL aspects of lightweight transactions,
such as grammar, null semantics, batch semantics, result set
format, and so on.

For now, comment out unicode tests: test output depends
on libjsoncpp version in use.
