The Bloom filter used for path limited history traversal was broken on systems whose "char" is unsigned; update the implementation and bump the format version to 2. * tb/path-filter-fix: bloom: introduce `deinit_bloom_filters()` commit-graph: reuse existing Bloom filters where possible object.h: fix mis-aligned flag bits table commit-graph: new Bloom filter version that fixes murmur3 commit-graph: unconditionally load Bloom filters bloom: prepare to discard incompatible Bloom filters bloom: annotate filters with hash version repo-settings: introduce commitgraph.changedPathsVersion t4216: test changed path filters with high bit paths t/helper/test-read-graph: implement `bloom-filters` mode bloom.h: make `load_bloom_filter_from_graph()` public t/helper/test-read-graph.c: extract `dump_graph_info()` gitformat-commit-graph: describe version 2 of BDAT commit-graph: ensure Bloom filters are read with consistent settings revision.c: consult Bloom filters for root commits t/t4216-log-bloom.sh: harden `test_bloom_filters_not_used()`
