    oeqa.utils.git.GitRepo: new arg to require topdir
    
    Add a new 'is_topdir' argument to the GitRepo init method which
    validates that the given path is the top directory of a Git repository.
    Without this argument GitRepo also accepts subdirectories of a Git
    repository (in which case GitRepo will point to the parent directory
    that is the top directory of this repository) which may have undesired
    in some cases.
