390673c322 Use properties to obtain an executor's execution context. 
Rather than using a context() member function, query the executor's
execution::context_t property to obtain its associated execution
context:

    asio::execution_context& context
      = asio::query(my_io_executor, asio::execution::context);

165ea38ac8 Use properties to track outstanding work against an io_context. 
When using standard executors, work is tracked by requiring (or
preferring) an executor with the execution::outstanding_work.tracked
property. This replaces executor_work_guard and make_work_guard() with
code of the form

    asio::io_context io_context;
    auto work = asio::require(io_context.get_executor(),
        asio::execution::outstanding_work.tracked);

To explicitly reset work, store the returned work-tracking executor in
an any_io_executor object:

    asio::any_io_executor work
      = asio::require(io_context.get_executor(),
          asio::execution::outstanding_work.tracked);

and then assign an empty executor into the object when done:

    work = asio::any_io_executor();

408168d7d4 Use an any_executor<> as the polymorphic executor for I/O objects. 
The asio::any_io_executor type alias has been added as the default
runtime-polymorphic executor for all I/O objects. This type alias points
to the execution::any_executor<> template with a set of supportable
properties specified for use with I/O.

If required for backward compatibility, ASIO_USE_TS_EXECUTOR_AS_DEFAULT
can be defined. This changes the asio::any_io_executor type alias to
point to the Networking TS-based runtime-polymorphic asio::executor
class instead.

6080760b80 Test for native I/O executors in detail::handler_work<>. 
The detail::io_object_executor wrapper has been removed, and the job of
detecting, and optimising for, native I/O executors is now performed
directly in the detail::handler_work implementation.

480a336189 Add single-buffer optimisation for descriptor read and write. 
When we can determine at compile time that the user has supplied a
single buffer, use read/write rather than readv/writev, as the former
system calls can be faster.
