Here is V2 of Part 2 of my Builtin FSMonitor series.

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.

Jeff Hostetler (5):
  fsmonitor: enhance existing comments
  fsmonitor-ipc: create client routines for git-fsmonitor--daemon
  fsmonitor: config settings are repository-specific
  fsmonitor: use IPC to query the builtin FSMonitor daemon
  fsmonitor: update fsmonitor config documentation
