* Use consistent Jinja whitespace control `{%- ... -}`
* Improve debug output (comments & whitespace control)
* Use exact state names with TOFS `files_switch`
* Add `ssh_known_hosts_src` to `defaults` (for consistency)
* Restrict `pillar.example` changes to TOFS only
* Use `fire_banner` in `pillar.example` to indicate available template

* Fix #162
* Check for any number of tabs after the keyword
* If found, replace them by a single space to match the `separator` used
  in the `ini_options.present` state

remove duplicated 'pillar.get' calls to retrieve the sshd_config and ssh_config pillars.

Closes #153.

* ssh_config: properly render host options (fixes #145)

* ssh_config: whitespace optimization (fixes #145)

added possibility to configure server version and client version
with pillar example

Change the require_ins used by the key management states in the
config.sls to be conditional based on whether the sshd_config
is managed by the formula

Fixes #130

* Pillar openssh.known_hosts_salt_ssh

* Dropped ill-named file

* Fixed aliasing of host names

* Improved pillar.example

* Opt-in to include localhost

* pillar/known_hosts_salt_ssh: clear cache in run()

* Dropped forgotten debugging output

* Add map for debian

closes #123

* drop default values (fixes #102)
* hmac-ripemd160 was dropped in 7.6

This prevents a verbatim version being added to end of file that will
cause the parsing to fail.

This is was introduced in 5.9, and is default in 6.1.

- generate before running check_mk on the sshd_config
- set permissions on private key
- cope with empty keys

OpenSSH's Match declarations are applied first-match-wins. However, we
can't safely define two Matches that might overlap unless we first sort
the keys, as Python (and Jinja) dicts don't guarantee the order of
dict keys,

We also won't scramble the match sequence every time the user adds,
removes or renames a match, and so we give the user clearer, more
concise diffs as when they apply changes.

Finally, we leave a comment on the Match line identifying where the
Match rule came from, to assist in troubleshooting.

Support complex compound matches in Match criteria. For example, be able
to match against multiple Users for a given Match, or be able to match
against address ranges. Or Groups. Or any combination thereof.

Support for matching users can take one of several different appearances
in pillar data:

sshd_config:
  matches:
    match_1:
      type:
        User: one_user
      options:
        ChrootDirectory: /ex/%u
    match_2:
      type:
        User:
          - jim
          - bob
          - sally
      options:
        ChrootDirectory: /ex/%u
    match_3:
      type:
        User:
          jim: ~
          bob: ~
          sally: ~
      options:
        ChrootDirectory: /ex/%u

Note the syntax of match_3. By using empty dicts for each user, we can
leverage Salt's pillar mergine. If we use simple lists, we cannot do
this; Salt can't merge simple lists, because it doesn't know what order
they ought to be in.

The fix introduced in 678cc9066c
suppresses the PrintLastLog directive for FreeBSD 10.3.
SSH on FreeBSD 11.0 also does not support PrintLastLog, so this
change suppresses it for any version >= 10.3.
