This patch overhauls the FAIL* server code to leverage Boost asio to be able to handle a large number of clients (>4000). In this implementation the server is now single threaded. I've not encountered any problems with this for up to about 10k clients. Boost ASIO can also be used multithreaded, but I assume the FAIL* internal data structures (Synchronized*) will become a bottleneck first. The code now additionally depends on Boost Coro and Boost Context, as well as a C++ 14 compiler, although the only C++14 feature required is a lambda capture with initializer, such as [ x = std::move(x) ]. gcc-4.9.2 does this. The code could (and probably should) be cleaned up more. Comments are wordy, code is unnecessary now (multiple server threads), code is not self-contained (headers spread dependencies), many ifdef's (server performance measuring should be runtime rather than a compile time option), and much more. But for this patch I was going for a minimal changeset the get the functionality in, to have an easier review. Alas, FAIL* has no Unit-test suite to run the changes against. To handle such a large number of clients more changes were necessary, for example server status output is now performed every 1s, instead for every request. The class Minion was removed completely; the only thing it was doing was encapsulate an int. The server has now a runtime-configurable port, or it can select a free port on its own if none is specified. This requires the CampaignManager to add a port argument and instantiate the JobServer dynamically. Change-Id: Iad9238972161f95f5802bd2251116f8aeee14884
