Fix failing jenkins test cases
Add detection for file size with static memory
Account for cert without pathLen constraint set including test cases
Resolve OCSP case and test where cert->pathLen expected to be NULL
1. Check the path length between an intermediate CA cert and its
signer's path length.
2. Always decode the path length if present and store it in the decoded
certificate.
3. Save the path length into the signer list.
4. Path length capped at 127.
5. Added some test certs for checking CA path lengths.
