e618857ff3 Add associator trait. 
The associator trait is used to generically forward associators, such as
associated_executor<> and associated_allocator<>, through intermediate
completion handlers. For example:

    template <typename Handler>
    struct intermediate_handler
    {
      Handler handler_;

      template <typename... Args>
      void operator()(Args&... args)
      {
        // ...
      }
    };

    namespace boost {
    namespace asio {

      template <
          template <typename, typename> class Associator,
          typename Handler,
          typename DefaultCandidate>
      struct associator<
          Associator,
          intermediate_handler<Handler>,
          DefaultCandidate>
      {
        using type =
          typename Associator<Handler, DefaultCandidate>::type;

        static type get(
            const intermediate_handler<Handler>& h,
            const DefaultCandidate& c = DefaultCandidate()) noexcept
        {
          return Associator<Handler, DefaultCandidate>::get(
              h.handler_, c);
        }
      };

    } // namespace asio
    } // namespace boost

26d1132d3d Increase number of cached memory slots for default recycling allocator. 
The number of per-thread slots may be configured at compile time by
defining ASIO_RECYCLING_ALLOCATOR_CACHE_SIZE to a non-negative integer.
If not defined, the default recycling allocator uses two slots.

bb8b2e2832 Make allocators respect alignment requirements. 
This is important when completion handlers contain over-aligned members,
for example when captured in a lambda.

This uses operator new() with alignment support if available,
and falls back to Boost Align (again, if available).

6bd1e1932a Prevent blocking.always from being used with strand<>. 
Previously, calling `require(E, blocking.always)` on a strand E compiled
but produced incorrect behaviour. Now, `require(E, blocking.always)`
will no longer compile. Furthermore, when used with an always-blocking
inner executor, the strand will report its blocking property as
blocking.possibly.

739109cacb The executor must be copied when an I/O object is move-assigned. 
The moved-from I/O object needs to be left in the same state as if
constructed with a valid executor but without a resource.

2c50cd1e42 Fix outstanding_work.tracked executor move assignment. 
Move assignments for io_context and thread pool executors are missing
the logic present in copy assignments that finishes work on old contexts.
This causes the following example to hang:

int main()
{
    asio::static_thread_pool tp1{1},tp2{1};
    {
        auto work = asio::prefer(tp1.get_executor(),
            asio::execution::outstanding_work.tracked);
        work = asio::prefer(tp2.get_executor(),
            asio::execution::outstanding_work.tracked);
    }
    tp1.join();
    tp2.join();
}
