Without this change, importing map.jinja in config files (as opposed to
SLS files) causes a rendering error because `slspath` isn't defined.
The `salt_settings.key_url` variable gets used only in
`salt/pkgrepo/debian/init.sls`.

This adds some minimal support for Windows minions.

This restores the original structure/behavior of the
`salt_formulas` Pillar key.

issue #180

- When it's iterable, the minion could be running on the master
- When it's a string, there's no advantage over just specifying
  `salt:minion:master`

This makes it easier for users to check the status of jobs that ran into
a timeout.

Jinja macros are not actually functions.  The only thing they can return
is a string.  In order to return structured data, the callee must
serialize it, and the caller must deserialize it.  This state formula
uses YAML as the intermediary, hence the occurrence of both the
`|yaml` (callee) and `|load_yaml` (caller) filters in its code.

The post-render "mapping values are not allowed here" error in
*salt/formulas.sls* or the broken rendering of
*salt/files/master.d/f_defaults.conf* happens because invocations of the
`formulas_git_opt` macro in several Jinja `set` statements do not get
deserialized, resulting in the trailing newline followed by three dot
characters (`...`), which YAML uses to signal the end of a document.
Correcting these rendering errors requires adding the necessary
deserialization code at those locations (i.e., filtering the macro call
through `|load_yaml`).

This test isn't available in certain popular versions of Jinja (namely the one
installed by default in CentOS 6).

Also watch salt-api pkg instead of salt-master one.

With a simple pillar like this::

    $ sudo salt-call --config-dir /srv/etc/bootstrap --pillar-root /srv/pillar pillar.get salt:pillar_roots
    local:
        ----------
        base:
            - /srv/pillar

This was generated in /etc/salt/master.d/f_defaults.conf::

    # highstate format, and is generally just key/value pairs.
    pillar_roots:base:- /srv/pillar
    #

Resulting in parse errors by salt::

    $ sudo salt '*' state.highstate
    [ERROR   ] Error parsing configuration file: /etc/salt/master.d/f_defaults.conf - while scanning a simple key
      in "<string>", line 531, column 1:

On FreeBSD salt-ssh gets bundled into a single package with the other
SaltStack components (minion, master, etc.).
