/**
* Determine whether a reflog entry should be created for the given reference.
*
* Whether or not writing to a reference should create a reflog entry is
* dependent on a number of things. Most importantly, there's the
* "core.logAllRefUpdates" setting that controls in which situations a
* reference should get a corresponding reflog entry. The following values for
* it are understood:
*
* - "false": Do not log reference updates.
*
* - "true": Log normal reference updates. This will write entries for
* references in "refs/heads", "refs/remotes", "refs/notes" and
* "HEAD" or if the reference already has a log entry.
*
* - "always": Always create a reflog entry.
*
* If unset, the value will default to "true" for non-bare repositories and
* "false" for bare ones.
*
* @param out pointer to which the result will be written, `1` means a reflog
* entry should be written, `0` means none should be written.
* @param db The refdb to decide this for.
* @param ref The reference one wants to check.
* @return `0` on success, a negative error code otherwise.
