Limit ASN.1 constructed types recursive definition depth
Constructed types with a recursive definition (such as can be found in
PKCS7) could eventually exceed the stack given malicious input with
excessive recursion. Therefore we limit the stack depth.
CVE-2018-0739
Credit to OSSFuzz for finding this issue.
