Merge branch 'maint'
* maint: Correct access flag handling in sftpd Client fallbacks to ipv4 if connection is refused with ipv6 Cleaned up code so that ssh_file can become a template for a documented ssh_keys behavior Test case maintenance Better handling of IPv6 Ssh daemon handles RSA host keys Removed no longer needed code Use the public_key application for all public key handling
