As methods allows user to set only public part I would like to propose 
to add new key method "...set0_privkey" to set just private key.
This will allow to avoid duplicate of key public part between get0 and 
set0 key methods.


For protocol "0009-sshkey.c-opaque-DSA-structure.patch" is practical 
sample of an upgrade to 1.1 API. RSA is similar.
