c481f9dafd Fix gssapi credential handling. 
- Properly acquire and inquitre credentials to get the list of available
credentials.
- Avoid enforcing a specific username it breaks some use cases (k5login).
- Remove confusing references to delegated credentials as there is no code
that actually uses delegated credentials in the initialization case.

13c4499449 session: Always request POLLIN 
The assumption is that if libssh functions are being invoked, we want

4cc7f4ad03 Add ssh_get_poll_flags() 
For integration with an external mainloop, we need to know how to
replicate libssh's internal poll() calls.  We originally through
ssh_get_status() was that API, but it's not really - those flags only
get updated from the *result* of a poll(), where what we really need
is to know how libssh would *start* a poll().

754152aa22 server: Fix ssh_execute_server_callbacks() client execution 
When the public key auth handler is executed and returns SSH_OK,
ssh_execute_server_callbacks() still runs some client callbacks,
which may set rc to SSH_AGAIN, which triggers a default reply on
auth, denying auth.

d4f5a0e6ab server: fix pubkey reply for key probes 
Per RFC 4252, it is required to send back only one of either
SSH_MSG_USERAUTH_PK_OK or SSH_MSG_USERAUTH_FAILURE for public
key probes.

Update the handling of 'auth_pubkey_function' to send back PK_OK
instead of SSH_MSG_USERAUTH_SUCCESS for the case that the state
of the message at hand is SSH_PUBLICKEY_STATE_NONE.

With this change, it is now possible to process an initial key probe
and then subsequent signature validation using the server callbacks.
