Move fsmonitor config settings to a new and opaque `struct fsmonitor_settings` structure. Add a lazily-loaded pointer to this into `struct repo_settings` Create an `enum fsmonitor_mode` type in `struct fsmonitor_settings` to represent the state of fsmonitor. This lets us represent which, if any, fsmonitor provider (hook or IPC) is enabled. Create `fsm_settings__get_*()` getters to lazily look up fsmonitor- related config settings. Get rid of the `core_fsmonitor` global variable. Move the code to lookup the existing `core.fsmonitor` config value into the fsmonitor settings. Create a hook pathname variable in `struct fsmonitor-settings` and only set it when in hook mode. Extend the definition of `core.fsmonitor` to be either a boolean or a hook pathname. When true, the builtin FSMonitor is used. When false or unset, no FSMonitor (neither builtin nor hook) is used. The existing `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 and global visibility leads to confusion when we add the IPC-based provider. So lets hide the details in fsmonitor-settings.c and let it decide which provider to use in the case of multiple settings. This avoids cluttering up repo-settings.c with these private details. A future commit in builtin-fsmonitor series will add the ability to disqualify worktrees for various reasons, such as being mounted from a remote volume, where fsmonitor should not be started. Having the config settings hidden in fsmonitor-settings.c allows such worktree restrictions to override the config values used.
