9e8e5f5cb2 knownhosts: Use ssh_mkdirs() instead of ssh_mkdir()
Previously, if the path to known_hosts file set through
SSH_OPTIONS_KNOWNHOSTS included missing directories,
ssh_session_update_known_hosts() would fail.  The added test case checks
that this is not the case anymore.

The logic of checking if the directory is accessible before creating it
was replaced by creating the directory if opening the file failed.  This
is to minimize the risk of TOCTOU race conditions.

1fd68ec732 kex: Do not ignore keys in known_hosts files
Previously, if the SSH_OPTIONS_HOSTKEYS option was set by any mean,
including the client configuration file, the keys in known_hosts files
wouldn't be considered before advertising the list of wanted host keys.

This could result in the client requesting the server to provide a
signature using a key not present in the known_hosts files (e.g. when
the first wanted algorithm in SSH_OPTIONS_HOSTKEYS is not present in the
known_hosts files), causing a host key mismatch and possible key
rejection.

Now, the keys present in the known_hosts files are prioritized over the
other wanted keys.  This do not change the fact that only keys of types
present in the list set in SSH_OPTIONS_HOSTKEYS will be accepted and
prioritized following the order defined by such list.

The new wanted list of hostkeys is given by:
 - The keys present in known_hosts files, ordered by preference defined
   in SSH_OPTIONS_HOSTKEYS.  If the option is not set, a default order
   of preference is used.
 - The other keys present in the same option are appended without adding
   duplicates.  If the option is not set, the default list of keys is
   used.
