Changes between 0.9.8k and 1.0 [xx XXX xxxx]
+ *) In BIO_pop() and BIO_push() use the ctrl argument (which was NULL) to
+ indicate the initial BIO being pushed or popped. This makes it possible
+ to determine whether the BIO is the one explicitly called or as a result
+ of the ctrl being passed down the chain. Fix BIO_pop() and SSL BIOs so
+ it handles reference counts correctly and doesn't zero out the I/O bio
+ when it is not being explicitly popped. WARNING: applications which
+ included workarounds for the old buggy behaviour will need to be modified
+ or they could free up already freed BIOs.
+ [Steve Henson]
+
*) Rename uni2asc and asc2uni functions to OPENSSL_uni2asc and
OPENSSL_asc2uni the original names were too generic and cause name
clashes on Netware.
