* Fix warnings * Port cmake scripts to linux * Add command line options for running test suites * Add examples to CMakeLists * Return std::uint64_t from writer::content_length * basic_parser::write takes asio::const_buffer instead of pointer and size * Turn message test back on now that it passes * Rename to http::headers, use std::allocator, remove http_headers * http::message::method is now a string * Refactor to_string for ConstBufferSequence * Remove chunk_encode from the public interface * Initialize members for default constructed iterators * Disallow default construction for dependent buffer sequences Refactor http::message serialization: * Serialization no longer creates a copy of the headers and modifies them * New function prepare(), sets Connection, Transfer-Encoding, Content-Length based on the body attributes and caller options. Callers can use prepare() to have the fields set automatically, or they can set the fields manually. * Use write for operator<< * Tests for serialization
