goalc: Add TCP server socket in REPL process (#1335)

* goalc: cleanup goalc's main method and add nrepl listener socket * deps: add standalone ASIO for sockets * lint: formatting * common: make a common interface for creating a server socket * goalc: setup new repl server * deps: remove asio * goalc: debug issues, nrepl is working again * git: rename files * attempt to fix linux function call * test * scripts: make the error message even more obvious.... * goalc: make suggested changes, still can't reconnect properly * game: pull out single-client logic from XSocketServer * nrepl: supports multiple clients and disconnection/reconnects * goalc: some minor fixes for tests * goalc: save repl history when the compiler reloads * common: add include for linux networking * a few small changes to fix tests * is it the assert? * change thread start order and add a print to an assert Co-authored-by: water <awaterford111445@gmail.com>
