Changes between 0.9.3a and 0.9.4
*) New functions RSA_get_default_method(), RSA_set_method() and
RSA_get_method(). These allows replacement of RSA_METHODs without having
to mess around with the internals of an RSA structure.
[Steve Henson]
*) Fix memory leaks in DSA_do_sign and DSA_is_prime.
Also really enable memory leak checks in openssl.c and in some
test programs.
