Move FSMonitor config settings to a new `struct fsmonitor_settings` structure. Add a lazily-loaded pointer to `struct repo_settings`. Create `fsm_settings__get_*()` getters to lazily look up fsmonitor- related config settings. Get rid of the `core_fsmonitor` global variable, and add support for the new `core.useBuiltinFSMonitor` config setting. Move config code to lookup the existing `core.fsmonitor` value to `fsmonitor-settings.[ch]`. The `core_fsmonitor` global variable was used to store the pathname to the FSMonitor hook and it was used as a boolean to see if FSMonitor was enabled. This dual usage will lead to confusion when we add support for a builtin FSMonitor based on IPC, since the builtin FSMonitor doesn't need the hook pathname. Replace the boolean usage with an `enum fsmonitor_mode` to represent the state of FSMonitor. And only set the pathname when in HOOK mode. Signed-off-by: Jeff Hostetler <jeffhost@microsoft.com>
