This should not be a problem for well-behaving clients that do not
append the ext-info-c to the rekey, but if they do, we should not
send it either.

If the hostkey type was not in the list of acceptable hostkey
types, the function failed to set the error state. Due to the
fact that the calling function ssh_packet_process() does not
handle the SSH_ERROR return code, the newkeys packet from the
server was silently ignored, stalling the connection until a
timeout occurred.

This will allow to use the same configuration in client applications
including the users aliases or system wide cryptographic configuration.
As the configuration parsing is the last thing before doing the
actual connection, it might overwrite previously set options.
If this is not intended, the client application can
ask the configuration files to be parsed before setting some other
options that should not ve overwritten. The code ensures that
the configuration is not parsed again.

If either one is missing at this point, fill it with default vaules in
ssh_options_apply().
Previously, when setting up only knownhosts, global_knownhosts file
was left pointing to NULL and the ssh_known_hosts_read_entries()
was trying to open NULL file which is invalid.
