Riak bugfixes

Defines memory and CPU facts:
- memfree_mb
- memtotal_mb
- swapfree_mb
- swaptotal_mb
- processor (a list)
- processor_cores
- processor_count
- devices

As a matter of fact, on NetBSD, it is possible to get memory, swap and
processor facts exactly as on Linux. Tested on NetBSD-5, NetBSD-6 and
NetBSD-6.1 (without Linux emulation).

Allow specification of erlang node name for rabbitmq_user/vhost/parameter actions.

Avoid crash in module_common when the file cannot be moved/copy

performance optimization in inventory.groups_list()

don't calculate all hosts for every parent group of every group
when that parent group was already in the cache

for fetching riak stats.

Documentation for keystone_user

hide magic variables used bin/ansible output

'verbose_override' and 'verbose_always'

Updated the module with proper documentation.

Update rabbitmq_user/vhost/parameter to pass the node to rabbitmqctl using -n flag to rabbitmqctl rather than setting the environment variable.

Fix bug with include-level vars and sudo_user.

Fixes apt_repository always reporting file uri repos as changed

Allow virtualenv_command argument of the pip module to be a pathname

Fixes #2991: Service module pattern argument ignored.

Fetch destination path can now be overriden.

Make pkgng and with_items result in a single module call.

Fix pip module documentation (YAML quoting)

add basename and dirname to the core jinja2 filters

Ensure the tmp_path is sufficiently open.

pip module -- sudo_user permission problem fix

Fixes #2924: User creation always reports 'changed'

Plug-ins loaded from top-level plug-in directory

Make debug module always verbose in playbooks

Created a new flag 'verbose_always' handled by
on_ok callback, similar to the 'verbose_override'
flag used by the setup module.

PluginLoader._get_paths, as of 391fb98e, was only finding plug-ins that
were in a subdirectory of one of the basedirs (i.e. in a category
directory).  For example, action_plugins/foo.py would never be loaded,
but action_plugins/bar/foo.py would work.

This makes it so that "uncategorized" plug-ins in the top level of a
directory such as action_plugins will be loaded, though plug-ins in a
"category" subdirectory will still be preferred.  For example,
action_plugins/bar/foo.py would be preferred over action_plugins/foo.py.
