Function git_odb::alternate::resolve

pub fn resolve(
    objects_directory: impl Into<PathBuf>
) -> Result<Vec<PathBuf>, Error>

Given an objects directory, try to resolve alternate object directories possibly located in the ./info/alternates file into canonical paths. If no alternate object database was resolved, the resulting Vec is empty (it is not an error if there are no alternates). It is an error once a repository is seen again as it would lead to a cycle.
