[PATCH 00/14] tree-wide: small fixes for memory leaks

This is a collection of various otherwise unrelated tree-wide fixes for memory leaks.

In fixing more targeted memory leaks in specific areas I've run into small leaks here & there. Rather than submit e.g. a 2-series patch for just small bundle leaks, the same for range-diff etc. I thought it made sense to submit these together.

Ævar Arnfjörð Bjarmason (14):
  index-pack: fix memory leaks
  merge-base: free() allocated "struct commit **" list
  diff.c: free "buf" in diff_words_flush()
  urlmatch.c: add and use a *_release() function
  remote-curl.c: free memory in cmd_main()
  bundle: call strvec_clear() on allocated strvec
  transport: stop needlessly copying bundle header references
  submodule--helper: fix trivial leak in module_add()
  commit-graph: fix memory leak in misused string_list API
  commit-graph: stop fill_oids_from_packs() progress on error and free()
  lockfile API users: simplify and don't leak "path"
  range-diff: plug memory leak in common invocation
  range-diff: plug memory leak in read_patches()
  repository.c: free the "path cache" in repo_clear()
