Changes between 0.9.8k and 1.0 [xx XXX xxxx]
*) Extensive audit of libcrypto with DEBUG_UNUSED. Fix many cases where
return value is ignored. NB. The functions RAND_add(), RAND_seed(),
BIO_set_cipher() and some obscure PEM functions were changed so they
can now return an error. The RAND changes required a change to the
RAND_METHOD structure.
[Steve Henson]
*) New macro __owur for "OpenSSL Warn Unused Result". This makes use of
a gcc attribute to warn if the result of a function is ignored. This
is enable if DEBUG_UNUSED is set. Add to several functions in evp.h
