fix#581
* request and response headers now have convenience
constructors so important fields like method, target,
result, and version may be set upon construction.
Actions Required:
* Evaluate each message constructor call site and
adjust the constructor argument list as needed.
fix#185, fix#489
* SSE4.2 is detected
* basic_parser uses SSE4.2 if available
* basic_parser tries to parse on the initial buffer and if
it does not find the end of header it shifts to a new
strategy of waiting for the end of header to defeat
slow loris attacks. This coincidentally is also faster
than the previous algorithm.
`put` returns the number of bytes actually transferred
from the input buffers.
Actions Required:
* Return the number of bytes actually transferred from the
input buffers in user defined `Body::writer::put` functions.
fix#550
* default body limits are now 1MB/8MB
* default header limit is 8KB
Actions Required:
* Call body_limit and/or header_limit as needed to adjust the
limits to suitable values if the defaults are insufficient.
The is_deferred nested type is removed from the BodyReader
requirements.
Performance for sending messages with `file_body` was cut
almost in half with is_deferred as `std::true_type` since
it caused double the number of socket writes. If the
deferred behavior is absolutely necessary, callers can get
the same effect by manually sending the headers first.
Actions Required:
* Callers who need the behavior of is_deferred as `std::true_type`
should manually construct a serializer and serialize the header
first, followed by the body.
fix#322
The new callback is informed of all frame types including close.
Actions Required:
* Change calls to websocket::stream::ping_callback to use
websocket::stream::control_callback
* Change user defined ping callbacks to have the new
signature and adjust the callback definition appropriately.
