Jeff Hostetler d2bd862e7a fsmonitor-ipc: create client routines for git-fsmonitor--daemon
Create fsmonitor_ipc__*() client routines to spawn the built-in file
system monitor daemon and send it an IPC request using the `Simple
IPC` API.

Stub in empty fsmonitor_ipc__*() functions for unsupported platforms.
