Changes between 0.9.6 and 0.9.7 [xx XXX 2000]
*) Fix to uni2asc() to cope with zero length Unicode strings.
These are present in some PKCS#12 files.
[Steve Henson]
*) Finish off removing the remaining LHASH function pointer casts.
There should no longer be any prototype-casting required when using
the LHASH abstraction, and any casts that remain are "bugs". See
