David Benjamin fb2c6f8c85 ASN1_get_object should not accept large universal tags. 
The high bits of the type get used for the V_ASN1_NEG bit, so when used with
ASN1_ANY/ASN1_TYPE, universal tags become ambiguous. This allows one to create
a negative zero, which should be impossible. Impose an upper bound on universal
tags accepted by crypto/asn1 and add a test.
