Implement server-side support for sk-ecdsa U2F-backed keys (#142)
* Implement server-side support for sk-ecdsa U2F-backed keys

* Fix out-of-bounds read on normal ecdsa-sha2-[identifier] keys

* Fix one more potential out-of-bounds read

* Check if nistp256 curve is used in sk-ecdsa-sha2- key

It's the only allowed curve per PROTOCOL.u2f specification

* Implement server-side support for sk-ed25519 FIDO2-backed keys

* Keys with type sk-* make no sense as host keys, so they should be
disabled

* fix typo

* Make sk-ecdsa call buf_ecdsa_verify

This reduces code duplication, the SK code just handles the
different message format.

* Reduce sk specific code

The application id can be stored in signkey, then we don't need
to call sk-specific functions from svr-authpubkey

* Remove debugging output, which causes compilation errors with DEBUG_TRACE disabled

* Proper cleanup of sk_app
