API Changes:
`string_param`, which was previously the argument type when setting field values
has been replaced by `string_view`. Because of this, it is no longer possible to
set message field values directly as integrals.
Users are required to convert numeric arguments to a string type prior to calling
`fields::set` et. al.
Beast provides the non-allocating `to_static_string()` function for this purpose.
To set Content-Length field manually, call `message::content_length`.
fixes#1956
API Changes:
The file `core/buffers_adapter.hpp` has been removed along with the deprecated
alias typename `buffers_adapter`. Affected programs should use
`core/buffers_adapator.hpp` and the type `buffers_adaptor`.
refs #1934
API Changes:
The core/type_traits.hpp public header has been removed and along with it
the type trait is_completion_handler. Beast uses the CompletionHandler correctness
checks provided by Asio. In a c++20 environment, these convert to concept checks.
API Changes:
* Code that depends on mutable_data_type should be refactored to use
mutable_buffers_type. Classes affected are:
- buffers_adaptor
- flat_buffer
- flat_static_buffer
- multi_buffer
- static_buffer
refs #1934
API Changes:
basic_stream::expires_after used to take a nanosecond duration type argument. This
required users on systems where the steady_clock::duration_type was less accurate
to explicity duration_cast when calling this function, making code non-portable.
The duration type is now that of the embedded steady_clock.
Many thanks to @spdw for noticing this and providing a patch.

fix#1853, close#1859, close#1866
After calling the DynamicBuffer commit() function the
buffer returned from prepare() can be invalidated but
the ostream kept using it.

This brings file_win32 in sync with the documentation.
Previously, the path passed to open worked if encoded in the system
codepage (which is almost never UTF-8).
Now, the path must be encoded as UTF-8, as stated in the
documentation.
Adapt file tests so that for file_win32 all paths include a unicorn
character.
C++14 or later is required to support completion tokens that use
per-operation return type deduction. For C++11, a completion
token's async_result specialisation must still provide the nested
typedef `return_type`.
