Changed the type of `size` from `UINT` to `ULONG` in `BridgeWin32.c` to resolve a compiler warning (`-Wincompatible-pointer-types`). The `PacketGetAdapterNames` function expects a `PULONG` (a pointer to an `unsigned long`) for its second parameter, whereas `UINT` maps to `unsigned int`.
- 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().
