From 448be743350791d32764fac38f5d3c8ffda481b2 Mon Sep 17 00:00:00 2001

Subject: Initial support for pluggable public key ASN1 support. Process most
 public key ASN1 handling through a single EVP_PKEY_ASN1_METHOD structure and
 move the spaghetti algorithm specific code to a single ASN1 module for each
 algorithm.
