Filter all calls to formulas_git_opt through load_yaml

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`).

Fixed conflict with git-formula

Remove mapping test

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

Improve flexibility/quality of pygit2 state

Configure the salt-api service to start at boot time

Only watch salt-api package if install_packages=true

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

Fixed pillar_roots generation for salt-master.

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:

        ^

      in "<string>", line 532, column 1:

Add options for mult-master setup

Use the py27-pygit2 package when installing pygit2 on FreeBSD

Use the py27-GitPython package when installing GitPython on FreeBSD

Use the py27-salt package when installing salt-ssh on FreeBSD

This key defaults to a value of `python-git`.

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

Add support for GitPython and salt-ssh on FreeBSD masters

Done at the maintainer's request.

salt.api state fails

Seems there are several colons missing for salt.api to work correctly, hope I found all of them

This change tweaks the GitPython package installation state to support
alternate package names (on FreeBSD, it's called "py27-GitPython").
Also, on FreeBSD salt-ssh is included in the "py27-salt" package by
default, requiring an update to `distro_map`.

Fix stuff suggested by @iggy.
