The changed-path Bloom filter is improved using ideas from an
independent implementation.

* sg/commit-graph-cleanups:
  commit-graph: persist existence of changed-paths
  commit-graph: change test to die on parse, not load
  bloom: enforce a minimum size of 8 bytes
  commit-graph: check all leading directories in changed path Bloom filters
  commit-graph: check chunk sizes after writing
  commit-graph: simplify chunk writes into loop
  commit-graph: unify the signatures of all write_graph_chunk_*() functions
  commit-graph: place bloom_settings in context
  commit-graph: simplify write_commit_graph_file() #2
  commit-graph: simplify write_commit_graph_file() #1
  commit-graph: simplify parse_commit_graph() #2
  commit-graph: simplify parse_commit_graph() #1
  commit-graph: clean up #includes
  diff.h: drop diff_tree_oid() & friends' return value
  commit-slab: add a function to deep free entries on the slab
  commit-graph-format.txt: all multi-byte numbers are in network byte order
  commit-graph: fix parsing the Chunk Lookup table
  tree-walk.c: don't match submodule entries for 'submod/anything'
