This version has been rebased onto "next" because it collided with a change "repo-settings.c" from "ab/repo-settings-cleanup". And the third commit was updated to resolve those conflicts. It also requires "jh/builtin-fsmonitor-part1" which is now in "next". Part 2 contains: Client-side code to connect to a (yet to be developed) FSMonitor daemon over Simple IPC (using Named Pipes or Unix Domain Sockets). Updated config settings to allow the client to decide whether to use Simple IPC or the existing FSMonitor Hook API. This includes retiring the existing "core_fsmonitor" global variable that had confusing double-duty. Part 2 essentially enables client-side code to talk to different types of providers of FS change data. Processing of that data is unchanged. A builtin FSMonitor daemon will be added in a later patch series.
