Vinnie Falco 765cb22b48 Invoke callback on pings and pongs (API Change):
fix #248

This additionally invokes the pong callback for received pings, allowing
callers to more efficiently detect when a connection is still lively:

* pong_callback renamed to ping_callback
* Callback signature has an extra `bool` to indicate if the received
  control frame is a ping or pong.

Vinnie Falco 911617c43f Add permessage-deflate WebSocket extension:
This implements the permessage-deflate WebSocket
extension as described in HyBi Working Group
draft-ietf-hybi-permessage-compression-28:
https://tools.ietf.org/html/draft-ietf-hybi-permessage-compression-28

This extension allows messages to be compressed using
the raw "deflate" algorithm described in RFC 1951,
"DEFLATE Compressed Data Format Specification version 1.3":

Vinnie Falco 01e1fa2dc9 Implement asio dealloc-before-invoke guarantee:
fix #215

This change guarantees that temporary memory allocated
through the asio hooks by the Beast implementation is
deallocated before invoking the final handler when performing
composed operations.

The change is accomplished by replacing std::shared_ptr with
a thread-safe custom container handler_ptr to manage composed
operation state. The container tracks other instances which
manage the same object and resets them in a safe way before
invoking the final handler.

handler_ptr is provided as a public interface so that users of
this library can utilize the same idiom to write their own
composed operations.

Vinnie Falco e3848e7281 Refactor HTTP identifier names (API Change):
fix #171

Several names and  HTTP identifiers are renamed to be
more consistent, self-explanatory, and concise:

* "Fields" is a collection of HTTP header fields (rfc7230 section 3.2)
* "Header" is the Start Line plus Fields. Another way to look at it is,
  the HTTP message minus the body.
* `basic_fields` replaces `basic_headers`
* `fields` replaces `headers`
* `Fields` replaces `Headers` in template parameter lists
* `header` replaces `message_headers`
* `header::fields` replaces `message_headers::fields`

The changes are cosmetic and do not affect run-time behavior.

Vinnie Falco 6afa6afc98 Fix consuming_buffers value_type (API Change):
This fixes a bug where instantiations of consuming_buffers with
buffer sequence types whose value_type is not const_buffer or
mutable_buffer can cause compilation errors.

The function consumed_buffers is removed.

Vinnie Falco f98ec17121 Make chunk_encode public:
fix #154, fix #156

This adds public interfaces for transforming buffer
sequences into their chunk-encoded equivalents. The
transformations are O(1) in space and time.

Vinnie Falco 50bc9a58cd Refactor message and message_headers declarations:
message_headers is now a set of partial class template
specializations instead of a template class alias. This solves
a problem where template functions taking message_headers as a
parameter could not deduce argument types, since std::conditional
obscured the deduced context.

Both classes are refactored to share declarations using an #ifdef,
to eliminate an ugly set of extra declarations needed when building
the documentation.

Copy and move class special members are added.

A new function message::base() is provided which returns the
message_headers portion of a message.

Vinnie Falco 19f15046b0 Fixes and documentation for teardown and use with SSL:
This solves a problem where clang and gcc locate the deleted
version of teardown and async_teardown instead of the overloaded
version. It requires overloads to add `teardown_tag` into the signature
so that the rules for argument dependent lookup can find the
right function. Improve documentation of teardown requirements

The documentation is updated to clearly explain the need for including
<beast/websocket/ssl.hpp> to use SSL streams with WebSocket.

The default implementations of teardown and async_teardown now use
static_assert to alert the user of improper usage, with comments
providing guidance for resolving the error.
