PKCS#7: avoid NULL pointer dereferences with missing content
In PKCS#7, the ASN.1 content component is optional.
This typically applies to inner content (detached signatures),
however we must also handle unexpected missing outer content
correctly.
This patch only addresses functions reachable from parsing,
decryption and verification, and functions otherwise associated
with reading potentially untrusted data.
Correcting all low-level API calls requires further work.
CVE-2015-0289
