Taylor Blau ab14d0676c commit-graph: pass a 'struct repository *' in more places
In a future commit, some commit-graph internals will want access to
'r->settings', but we only have the 'struct object_directory *'
corresponding to that repository.

Add an additional parameter to pass the repository around in more
places.

Josh Steadmon 104de88675 fuzz-commit-graph: properly free graph struct
Use the provided free_commit_graph() to properly free the commit graph
in fuzz-commit-graph. Otherwise, the fuzzer itself leaks memory when the
struct contains pointers to allocated memory.

Jeff King c8828530b7 commit-graph: close descriptors after mmap
We don't ever refer to the descriptor after mmap-ing it. And keeping it
open means we can run out of descriptors in degenerate cases (e.g.,
thousands of split chain files). Let's close it as soon as possible.

Josh Steadmon 249dc53444 fuzz-commit-graph: initialize repo object
Various #DEFINE "constants" in commit-graph.c now depend on
the_hash_algo->rawsz, but this object must be initialized before it can
be used.

Josh Steadmon aa658574bf commit-graph, fuzz: add fuzzer for commit-graph
Break load_commit_graph_one() into a new function, parse_commit_graph().
The latter function operates on arbitrary buffers, which makes it
suitable as a fuzzing target. Since parse_commit_graph() is only called
by load_commit_graph_one() (and the fuzzer described below), we omit
error messages that would be duplicated by the caller.

Adds fuzz-commit-graph.c, which provides a fuzzing entry point
compatible with libFuzzer (and possibly other fuzzing engines).
