Eric Biggers	2b940bcde1	libbpf: Fix undefined behavior in {get,put}_unaligned_be32() ... These violate aliasing rules and may be miscompiled unless -fno-strict-aliasing is used. Replace them with the standard memcpy() solution. Note that compilers know how to optimize this properly.

Eric Biggers	367798a9cf	libbpf: Replace AF_ALG with open coded SHA-256 ... Reimplement libbpf_sha256() using some basic SHA-256 C code. This eliminates the newly-added dependency on AF_ALG, which is a problematic UAPI that is not supported by all kernels. Make libbpf_sha256() return void, since it can no longer fail. This simplifies some callers. Also drop the unnecessary 'sha_out_sz' parameter. Finally, also fix the typo in "compute_sha_udpate_offsets".
