This patch introduces the SQLServer system server. This service is supposed to be the only process/application talking to database storage. This makes things like locking and caching more reliable, easier to implement, and more efficient. In LibSQL we added a client component that does the ugly IPC nitty- gritty for you. All that's needed is setting a number of event handler lambdas and you can connect to databases and execute statements on them. Applications that wish to use this SQLClient class obviously need to link LibSQL and LibIPC.
