Jakub Jelen 4169be45eb pki: Allow filtering accepted public key types based on the configuration
This effectively allows to disable using the SHA2 extension, disable
other old public key mechanisms out of the box (hello DSA) or force
the new SHA2-based key algorithm types if needed.

This exposes the  default_methods  array from  kex.c.
