Fix up concurrent use of APIs
Code that is incorrectly using MessageDigest, Signature, or Mac in
multiple threads simultaneously could cause a SEGV if OpenSSL is
clearing out the MD_CTX at the same time another thread is trying to
write to it. Make sure we initialize a new MD_CTX after each run to
avoid crashing. The program using the instances concurrently is still
wrong and will most likely get inconsistent results.
Switch to using a context object instance to make sure we can hold a
reference to the object during the native call.
