  1. Fix potential DoS issue with p2c header 

    Unbounded p2c headers may be used to cause an application that accept
PBES algorithms to spend alot of resources running PBKDF2 with a very
high number of iterations.

Clamp the default maximum to 16384 (double the default of 8192).
An application that wants to use more iterations will have to chenge the
jwa default max.

Fixes CVE-2023-6681
