[ksba] Formatting of public keys

[Dmitry Eremin-Solenikov]

Hello,

I'm currently playing with adding GOST R 34.10/34.11 support in libksba.
I'm currently facing an issue with pubkey conversion from S-exp to DER.

I need to convert pubkeys differently depending on the hashing algo (old
or new one) used with the certificate. Is there a way to cleanly express that
in libksba?
