* Put AES ctx on the heap This forces people to use the ``ctx_release`` functions, because otherwise there will be leaks * Put fips202 on the heap * Add much more docs for fips202.h * fixup! Put fips202 on the heap * Put SHA2 on the heap-supporting API * Fix clang-tidy warnings * Fix unreachable free() in falcon * Fix McEliece8192128f-sse GNU Makefile
