_asn1_decode_simple_ber: restrict the levels of recursion to 3 



On indefinite string decoding, setting a maximum level of recursions
protects the BER decoder from a stack exhaustion due to large amounts
of recursion.

    It makes sense to me after inspecting some other changes in tmp-protect-ber-decoder-from-recursion2. What would be probably good to add is the description of dflags parameter of _asn1_decode_simple_ber, but maybe in different commit.
