- *Replace usage of boost::asio with [libevent2](http://libevent.org/)*. boost::asio is not part of C++11, so unlike other boost there is no forwards-compatibility reason to stick with it. Together with #4738 (convert json_spirit to UniValue), this rids Bitcoin Core of the worst offenders with regard to compile-time slowness. - *Replace spit-and-duct-tape http server with evhttp*. Front-end http handling is handled by libevent, a work queue (with configurable depth and parallelism) is used to handle application requests. - *Wrap HTTP request in C++ class*; this makes the application code mostly HTTP-server-neutral - *Refactor RPC to move all http-specific code to a separate file*. Theoreticaly this can allow building without HTTP server but with another RPC backend, e.g. Qt's debug console (currently not implemented) or future RPC mechanisms people may want to use. - *HTTP dispatch mechanism*; services (e.g., RPC, REST) register which URL paths they want to handle. By using a proven, high-performance asynchronous networking library (also used by Tor) and HTTP server, problems such as #5674, #5655, #344 should be avoided. What works? bitcoind, bitcoin-cli, bitcoin-qt. Unit tests and RPC/REST tests pass. The aim for now is everything but SSL support. Configuration options: - `-rpcthreads`: repurposed as "number of work handler threads". Still defaults to 4. - `-rpcworkqueue`: maximum depth of work queue. When this is reached, new requests will return a 500 Internal Error. - `-rpctimeout`: inactivity time, in seconds, after which to disconnect a client. - `-debug=http`: low-level http activity logging
