Beast.HTTP:

Browse Source 
New classes are introduced to represent HTTP messages and their
associated bodies. The parser interface is reworked to use CRTP,
error codes, and trait checks.

New classes:

* basic_headers

  Models field/value pairs in a HTTP message.

* message

  Models a HTTP message, body behavior defined by template argument.
  Parsed message carries metadata generated during parsing.

* parser

  Produces parsed messages.

* empty_body, string_body, basic_streambuf_body

  Classes used to represent content bodies in various ways.

New functions:

* read, async_read, write, async_write

  Read and write HTTP messages on a socket.

New concepts:

* Body: Represents the HTTP Content-Body.
* Field: A HTTP header field.
* FieldSequence: A forward sequence of fields.
* Reader: Parses a Body from a stream of bytes.
* Writer: Serializes a Body to buffers.

basic_parser changes:

* add write methods which throw exceptions instead
* error_code passed via parameter instead of return value
* fold private member calls into existing callbacks
* basic_parser uses CRTP instead of virtual members
* add documentation on Derived requirements for CRTP

impl/http-parser changes:

* joyent renamed to nodejs to reflect upstream changes
