Split private key PEM and normal PEM handling. Private key handling needs to link in stuff like PKCS#8. Relocate the ASN1 *_dup() functions, to the relevant ASN1 modules using new macro IMPLEMENT_ASN1_DUP_FUNCTION. Previously these were all in crypto/x509/x_all.c along with every ASN1 BIO/fp function which linked in *every* ASN1 function if a single dup was used. Move the authority key id ASN1 structure to a separate file. This is used in the X509 routines and its previous location linked in all the v3 extension code. Also move ASN1_tag2bit to avoid linking in a_bytes.c which is now largely obsolete. So far under Linux stripped binary with single PEM_read_X509 is now 238K compared to 380K before these changes.
