fix#941, fix#1016
`get_lowest_layer` is now a type alias for the
lowest layer instead of a struct with a nested type.
Actions required:
* Replace instances of `typename get_lowest_layer<T>::type`
with `get_lowest_layer<T>`.
fix#949
* New error codes are introduced for WebSocket failures
* More verbose messages for error codes
* Error codes are mapped to conditions for ease of testing
* error::failed and error::handshake_failed are deprecated (don't use)
Actions Required:
* Code which explicitly compares error_code values against the
constant `websocket::error::handshake_failed` should compare
against `websocket::condition::handshake_failed` instead.
* Code which explicitly compares error_code values against the
constant `websocket::error::failed` should compare
against `websocket::condition::protocol_violation` instead.
fix#849
This adds an additional `bool` template parameter to
`websocket::stream`:
* When deflateSupported is `true`, the stream will be capable
of negotiating the permessage-deflate websocket extension per
the configured run-time settings.
* When deflateSupported is `false`, the stream will never negotiate
the permessage-deflate websocket extension. Furthermore, all of the
code necessary for implementing the permessage-deflate extension
will be excluded from function instantiations. The resulting emitted
object code should be smaller.
fix#884
* BodyReader and BodyWriter constructors now require the header and
body elements to be passed as distinct header and value_type objects.
This enables the composition of body types, for example:
http::response<compressed_body<http::string_body>> res;
* The previous single-argument constructors are deprecated and will be
removed in a subsequent version.
Actions Required:
* Change user-defined instances of BodyReader or BodyWriter constructor
signatures to the two-argument form.
OR
* Define the macro BOOST_BEAST_ALLOW_DEPRECATED in the project (which
will accept both the new and the deprecated signatures).
Split the websocket read test to reduce compile time memory usage
by a small amount, which ought to be enough to let it compile in
a constrained environment like Travis.

* The handler_ptr constructor now provides the
strong exception guarantee.
* The signature for managed objects constructed by
`handler_ptr` receives a const reference to the handler.
Actions required:
* Change the constructor signature for state objects
used with handler_ptr to receive a const reference to
the handler.
This fixes a problem where an assert is generated or an
error is ignored when an invalid deflate stream is produced
after appending the final empty deflate block.
The function stream::control_callback now copies or moves
the callback. In some cases this may require a dynamic
allocation.
To avoid the possibility of a dynamic allocation, callers
may wrap their callback using `std::ref` before setting it.
Body::reader and Body::writer meanings are reversed, for
consistency with the names of the stream operations:
* Body::reader is used for read, read_some, async_read, async_read_some
* Body::writer is used for write, write_some, async_write, async_write_some
Actions Required:
* Swap the reader and writer names for user defined Body types
* Swap use of is_body_reader and is_body_writer
* Fields::writer replaces Fields::reader
* The FieldsWriter concept is renamed from FieldsReader
Actions Required:
* Rename reader to writer for user defined Fields
Some `basic_parser` member functions are renamed:
* chunked() was is_chunked()
* upgrade() was is_upgrade()
* keep_alive() was is_keep_alive()
Actions Required:
* Rename member function invocations at call sites
* The function has_content_length_impl is added to the
requirements of Fields.
Actions Required:
* Implement has_content_length_impl for user-defined Fields
fix#769
The following classes are removed:
* handler_type
* async_result
* async_completion
* is_dynamic_buffer
* is_const_buffer_sequence
* is_mutable_buffer_sequence
* handler_alloc
Actions Required:
* Use BOOST_ASIO_HANDLER_TYPE instead of handler_type
* Use BOOST_ASIO_INITFN_RESULT_TYPE instead of async_result
* Use boost::asio::async_completion
* Use boost::asio::is_dynamic_buffer
* Use boost::asio::is_const_buffer_sequence
* Use boost::asio::is_mutable_buffer_sequence
* boost::asio::associated_allocator_t replaces handler_alloc
