More linker bloat reorganisation:

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.

sure they are available in opensslconf.h, by giving them names starting
with "OPENSSL_" to avoid conflicts with other packages and by making
sure e_os2.h will cover all platform-specific cases together with
opensslconf.h.

I've checked fairly well that nothing breaks with this (apart from
external software that will adapt if they have used something like
NO_KRB5), but I can't guarantee it completely, so a review of this
change would be a good thing.

most of the old wrappers. A few of the old versions remain
because they are non standard and the corresponding ASN1
code has not been reimplemented yet.

Merge from the ASN1 branch of new ASN1 code
to main trunk.

Lets see if the makes it to openssl-cvs :-)

like Malloc, Realloc and especially Free conflict with already existing names
on some operating systems or other packages.  That is reason enough to change
the names of the OpenSSL memory allocation macros to something that has a
better chance of being unique, like prepending them with OPENSSL_.

This change includes all the name changes needed throughout all C files.
