Changes between 0.9.6 and 0.9.7 [xx XXX 2000]
*) Modify EVP_Digest*() routines so they now return values. Although the
internal software routines can never fail additional hardware versions
might.
[Steve Henson]
*) Clean up crypto/err/err.h and change some error codes to avoid conflicts:
Previously ERR_R_FATAL was too small and coincided with ERR_LIB_PKCS7
