Get rid of hazardous EVP_DigestInit_dbg/EVP_DigestInit case distinction (which does not work well because if CRYPTO_MDEBUG is defined at library compile time, it is not necessarily defined at application compile time; and memory debugging now can be reconfigured at run-time anyway).  To get the intended semantics, we could just use the EVP_DigestInit_dbg unconditionally (which uses the caller's __FILE__ and __LINE__ for memory leak debugging), but this would make memory debugging inconsistent.  Instead, callers can use CRYPTO_push_info() to track down memory leaks.

Also fix indentation, and add OpenSSL copyright.
