Mac/FreeBSD Network Facts implementation

Uses a generic BSD Network class, which uses ifconfig and
parses crap out of it.  Modifies the Network __new__
implementation to search further down the subclass

Fix apt module's boolean check to expect converted value

Fixes #2218.
Update various modules for check_mode

This updates the following modules to support check_mode:
* apt_key
* apt_repository
* easy_install
* pip - will always report changed due to the way it handles state
* seboolean
* selinux
* slurp - since nothing changes, it just adds that it supports
  check_mode
* subversion - reports changed when checking out new repo and
  when updating.
* supervisorctl
* svr4pkg

See issue #2114.
Fix CliRunnerCallbacks.on_file_diff in callbacks.py

When running ansible -C, I get a traceback that ends with
    AttributeError: Values instance has no attribute 'diff'
This fixes on_file_diff to behave similar to
PlaybookRunnerCallbacks.on_file_diff().

Adding support for OpenWrt
Restructured inheritance of BSD network classes

Now all BSD network classes directly inherit from Network as well as from the generic BSD network class.  This removes the need for itersubclasses().
Broke BSD ifconfig parser into chunks for subclassing

This allows minor changes to be handled by adding a new
parse line function to the subclass

    Fixed the service command not working

    On Ubuntu 1[02].04 the service name was not recognized because
    there is a SysV style init script, but not an upstart config file.

    Example: The `ntp` client.

    Also removed extra spaces at the end of the lines, while at it.
