supported. Add support in d2i_AutoPrivateKey().

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.

that are needed in the ASN.1 macros.  Hopefully, we can get rid of
those in an elegant way in the future.

that can automatically determine the type of a DER encoded
"traditional" format private key and change some of the
d2i functions to use it instead of requiring the application
to work out the key type.
