Plug or annotate remaining leaks that trigger while running the very basic set of tests. * ah/plugleaks: transport: also free remote_refs in transport_disconnect() parse-options: don't leak alias help messages parse-options: convert bitfield values to use binary shift init-db: silence template_dir leak when converting to absolute path init: remove git_init_db_config() while fixing leaks worktree: fix leak in dwim_branch() clone: free or UNLEAK further pointers when finished reset: free instead of leaking unneeded ref symbolic-ref: don't leak shortened refname in check_symref()
