[PATCH v2 0/6] Allow writing invalid OIDs into refs for testing purposes

this covers a few cases of direct filesystem access to the ref database in tests.

v2 folds in more fixes for making t1430 reftable-proof.

 * add REF_SKIP_REFNAME_VERIFICATION as well
 * upgrade some more bits of t1430

Han-Wen Nienhuys (6):
  test-ref-store: plug memory leak in cmd_delete_refs
  refs: update comment.
  refs: allow skipping OID verification
  refs: add REF_SKIP_REFNAME_VERIFICATION flag
  t1430: remove refs using test-tool
  t1430: create valid symrefs using test-helper
