Sometimes, `blkid` will incorrectly return no information about a block
device, even if it exists and has a valid filesystem. This causes the
*filesystem* module to fail if *force=no*. Instructing `blkid` to use
`/dev/null` as a cache file will force it to rescan the block device on
each run, making results more consistent.

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

  assert:

      - "lvol_result3.changed == True"

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)
