fix#431, fix#430
The read_some and async_read_some HTTP operations no longer
return the number of bytes that the caller should consume.
Instead, the bytes are automatically removed from the dynamic
buffer as indicated by the parser.
* header::result is a family of functions to replace header::status
* header interface now uses status enum and also ints
* reason-phrase is no longer stored unless the user explicitly
requests it.
* When serializing, the standard reason is used for the
corresponding status code unless the user has changed it.
The verb interfaces now use verb::unknown instead of
boost::optional<verb> == boost::none to indicate that
the request-method is an unrecognized string.
The http::header interface is modified to focus more on the
verb enum rather than the string. For recognized verbs, the
implementation stores an integer instead of the string.
Unknown verbs are still stored as strings.
* header::method now returns a verb
* header::method_string returns the method text
fix#404
Parsing and serialization interfaces have been fine tuned and unified.
For parsing these stream operations are defined:
* read
* read_header
* read_some
* async_read
* async_read_header
* async_read_some
For serialization these stream operations are defined:
* write
* write_header
* write_some
* async_write
* async_write_header
* async_write_some
fix#398
A new enum status is added for the status code.
The function obsolete_reason returns default reason phrasing.
If a response has an empty reason, the serializer will
automatically insert the default reason phrase for the
status code.
