New HTTP interfaces (API Change):

fix #123 fix #154 fix #265 This completely replaces the HTTP parser used to read and parse incoming messages. The new version is faster than the old one, and written in fewer lines. A summary of changes: * parse and async_parse renamed to read and async_read * basic_parser is optimized for linear buffers, use flat_streambuf for the best performance with these functions: - http::read - http::read_some - http::async_read - http::async_read_some * The overloads of read() and async_read() which take just a header have been removed, since they would throw away important parse metadata. * The derived class callbacks for basic_parser have been streamlined. All strings passed to callbacks are presented in their entirety, instead of being provided in pieces. These changes allow use-cases that were previously difficult or impossible, such as: - Efficient relaying - Late body type commitment - Expect: 100-continue handling
