When memory is released and reallocated, a random security value called a canary is written to the before/after area of memory, and if the value has been modified, the process is terminated (restarted) for safety, assuming it is a buffer overflow of the memory area. This feature may effectively prevent confidentiality or integrity violations in the event that some heap area overflow vulnerability is discovered in this system in the future.
- Hash() has been removed because it was ambiguous, Md5() and Sha0() are proper replacements.
- HMacMd5() and HMacSha1() now share a common implementation handled by the new Internal_HMac() function.
- NewMd() and MdProcess() now support plain hashing (without the key).
- NewMd(), SetMdKey() and MdProcess() now check the OpenSSL functions' return value and in case of failure a debug message is printed along with the error string, if available.
- SetMdKey()'s return value has been changed from void to bool, so that it's possible to know whether the function succeeded or not.
- MdProcess()' return value has been changed from void to UINT (unsigned int) and the function now returns the number of bytes written by HMAC_Final() or EVP_DigestFinal_ex().

Before, it would end up far in the future. Now it gets clamped
to 1970. This should be fine since dates before 1970 are not
actively used. If they are, then the UINT64 should be replaced
by the time64t in quite a few places.
