The postgresql_user module has several drawbacks:
* No granularity for privileges
* PostgreSQL semantics force working on one
  database at time, at least for Tables. Which
  means that a single call can't remove all the 
  privileges for a user, and a user can't be
  removed until all the privileges are removed, 
  forcing a module failure with no way to 
  work around the issue.

Changes:
* Added the ability to specify granular privileges
  for database and tables within the database
* Report if user was removed, and add an option to 
  disable failing if user is not removed.

Handle special files just like normal files

As discussed in #923

Fix off-by-one serial count (causing infinite loop for serial == 1).

Moved inventory scripts to the ansible/ansible-plugins repo so they can be updated independent of release.

Adds a thirsty=yes|no to the get_url module, such that if downloading a large file from the internet you can decide
whether to download it every time or not -- will replace only on change, or decide to not download.  The default
is thirsty=no which will not download every time by default.

The 'hostname' variable is then unicode, which breaks interpolating
stdout etc. contents into the output strings (they are bytes and cannot
be converted to Unicode using ASCII codec)

Paramiko does not allow Unicode strings as parameters, so encode
the command to UTF-8.

Test case:

ansible localhost -m raw -a 'echo ą'

(also tested on local and ssh transports without problems)

This is required to run commands containing non-ASCII characters, e.g.:

ansible localhost -m shell -a 'echo ą'

delegates.

Closes #905

Point to the proper config file

The global config file is loaded from /etc/ansible, not /etc

Fix setup module explosion when a route is empty. Closes #909

setup.py needs adjusting to ansible.runner.connections

Change the order the setup cache is used to update things, such that the example/playbooks/conditional_part1.yml file
works as advertised

Adds the 'serial' keyword to a playbook which controls how many hosts can be running through a playbook at a single time.
The default is 0, which means all hosts.  If set to 1, each host would run a playbook all the way through before moving
on the next host.  Fact gathering is still parallel, regardless of the serial setting.

Add pattern option to service module

Work with tun and p2p interfaces

Retrieve pip path after creating virtualenv

Fixes for postgresql_user to make it work with postgresql defaults and under Python 2.4

Syntax changes necessary to make test-module work with Python 2.4

Return both stdout and stderr on pip failures.
