[PATCH 00/11] built-ins: fix common memory leaks

This is a series of trivial leak-fixes which allows us to mark a significant number of new tests as entirely passing under SANITIZE=leak.

Now that 2da81d1efb0 (Merge branch 'ab/plug-leak-in-revisions', 2022-06-07) has landed we're going to have more & more cases where fixing just one leak will allow us to mark N tests as passing in their entirety. This is the first stepping stone on the way to that end.

Ævar Arnfjörð Bjarmason (11):
  check-ref-format: fix trivial memory leak
  clone: fix memory leak in copy_ref() call
  submodule.c: free() memory from xgetcwd()
  revert: free "struct replay_opts" members
  cat-file: fix a memory leak in --batch-command mode
  merge-file: refactor for subsequent memory leak fix
  merge-file: fix memory leaks on error path
  checkout: add a missing clear_unpack_trees_porcelain()
  gc: fix a memory leak
  cat-file: fix a common "struct object_context" memory leak
  pull: fix a "struct oid_array" memory leak
