Fix setup module to gather facts from PowerPC Macs.

Rename flatten function.

flatten(x) is used a lot in the various lookup plugins where in each it is slightly different. This is to make this name slightly more unique.

Fix fails on ubuntu due to missing /etc/motd

Tests functional on centos6, ubuntu1204 and ubuntu1310 now.

Some systems that we are testing on may not have /etc/motd. So we need to create a file that we can control and use that for the further tests.

Fixes #5869

lookup_plugins: loop over hashes

Tests good with the global variables:
```
users:
  alice:
    name: Alice
    id: 12345
  luna:
    name: Luna
    id: 23456
```

and playbook tasks:
```
- name: Print records.
  debug: msg="User {{ item.key }} is {{ item.value.name }}  {{ item.value.id }}"
  with_dict: users
```

Create a lookup plugin named dict that can be used to loop over hashes.
It converts a dict into a list of key-value pairs, with attributes named
"key" and "value."  Also adds a brief explanation and simple example to
the docs.

Fixes #5869

 Fixed up merge for the lvol module.

Conflicts:
	library/system/lvol

If you try to resize a lvol to the current size return a changed=False and don't fail.

Fix expires

This addresses GH-5165 and adds the ability to check if a lvol exists.

The tests for this don't fit nicely into the current integration tests so they are below.

```
---

- name: remove any existing lv=one of vg=main
  lvol: lv=one vg=main state=absent

- name: remove any existing lv=two of vg=main
  lvol: lv=two vg=main state=absent

- name: check to see if lv=one of vg=main exists
  lvol: lv=one vg=main state=present
  ignore_errors: true
  register: lvol_result0

- name: Assert that we will get a "No size given."
  assert:
    that:
      - "'No size given.' in lvol_result0.msg"

- name: create lv=one of vg=main sized 30g
  lvol: lv=one size=30g vg=main state=present
  register: lvol_result1

- name: Assert that we made changes."
  assert:
    that:
      - "lvol_result1.changed == True"

- name: check to see if lv=one of vg=main exists
  lvol: lv=one vg=main state=present
  register: lvol_result2

- name: Assert that we did not make changes."
  assert:
    that:
      - "lvol_result2.changed == False"

- name: remove lv=one of vg=main
  lvol: lv=one vg=main state=absent

- name: create lv=two of vg=main sized 30G
  lvol: lv=two size=30G vg=main state=present
  register: lvol_result3

- name: Assert that we made changes."
  assert:
    that:
      - "lvol_result3.changed == True"

- name: reduce lv=two of vg=main to 15G
  lvol: lv=two size=15G vg=main state=present
  register: lvol_result4

- name: Assert that we made changes."
  assert:
    that:
      - "lvol_result4.changed == True"

- name: increase lv=two of vg=main to 30G
  lvol: lv=two size=30G vg=main state=present
  register: lvol_result5

- name: Assert that we made changes."
  assert:
    that:
      - "lvol_result5.changed == True"

- name: create lv=two of vg=main sized 30G when already exists at 30G
  lvol: lv=two size=30g vg=main state=present
  register: lvol_result6

- name: Assert that we did not make changes."
  assert:
    that:
      - "lvol_result6.changed == False"

Merge branch '5853-python-2.5-apt_repository-fix' of https://github.com/timurbatyrshin/ansible into timurbatyrshin-5853-python-2.5-apt_repository-fix

Bugfixes:
* the remote_src param was not being converted to a boolean correctly,
  resulting in it never being used by the module as the default behavior
  was remote_src=True (issue #5581)
* the remote_src param was not listed in the generic file params, leading
  to a failure when the above bug regarding remote_src was fixed
* the delimiter should always end with a newline to ensure that the file
  fragments do not run together on one line

Fixes #5581

Correct assert and add with_items test

Vault rewrite, pass 1

Typo/Grammar fix.

allow ansible_ssh_private_key_file to be templated (thanks to benno)

This tests clean with the new integration tests.
