Functions to get keys from EVP_PKEY structures.

this will be used to clear up the horrible DN mess.

structure and decides what key to generate (if any). Not currently added to
the PBE algorithm list because it is largely untested.

AlgorithmIdentifier and make various ASN1 fixes.

integers was completely broken. Also added a NEG_PUBKEY_BUG compilation option
to compensate for public keys improperly encoded as negative integers.

script, translates function codes better and doesn't need the K&R function
prototypes to work (NB. the K&R prototypes can't be wiped just yet: they are
still needed by the DEF generator...). I also ran the script with the -rewrite
option to update all the header and source files.

openssl x509 -in cert.pem -text
on a certificate with some extensions in it.

This is the result of a "make errors" with the new error building functionality
in place.
