[PATCH 0/5] plugging some list-objects-filter leaks

The test I sent earlier in [1] fails the linux-leaks CI job, not because
it introduces new leaks, but just because it runs existing leaks in a
test marked as passing-leaks.

Of course we can drop the passing flag, but I figured it would probably
be an easy fix. Famous last words. It turned into quite a rabbit hole of
actual leaks (albeit small and bounded per process) and some
questionable memory ownership semantics.

Here's the series I came up with. I'm cc-ing Stolee as the last person
unfortunate enough to have touched this area. :)

  [1/5]: list_objects_filter_copy(): deep-copy sparse_oid_name field
  [2/5]: transport: deep-copy object-filter struct for fetch-pack
  [3/5]: transport: free filter options in disconnect_git()
  [4/5]: list_objects_filter_options: plug leak of filter_spec strings
  [5/5]: prepare_repo_settings(): plug leak of config values
