Changes between 0.9.6 and 0.9.7 [xx XXX 2000]
*) If signature or public key algorithm is unrecognized print out its
OID rather that just UNKOWN.
[Steve Henson]
*) Avoid coredump with unsupported or invalid public keys by checking if
X509_get_pubkey() fails in PKCS7_verify(). Fix memory leak when
PKCS7_verify() fails with non detached data.
