Inline nlohmann/json for the JSON parsing itself, and handle requests
with the same SCGI interface as XML-RPC.
Based off the work in https://github.com/jesec/rtorrent
This is a follow up to #1310. Apple and Solaris do not support MSG_NOSIGNAL, so disable this flag for these platforms until we find a better solution. Other platforms remain unaffected.
This commit resolves a scgi software crash when the scgi socket is closed before the message can be sent. It instructs `::send()` not to send a SIGPIPE termination signal. Instead the value -1 is returned and handled bellow. The SCgiTask is closed and a new one is sent to complete the task.

* Cleaned up main initialization, SCGI and polling code.
* Fixed a bug that would cause reading of a piece to hang if the incoming data contains only data up to the file boundary, but not the next file's data. The bug did not trigger if the file boundary and piece boundaries were the same.
