Improvements to wait_for module

get file/path facts via 'stat'

Added a provision for passing a server password to IRC

Add htpasswd module

expanduser on each component of plug-in paths

Remove redundant call to _get_path() in PluginLoader.find_plugin()

Fix the issue of easy_install ignoring virtualenv_site_packages=yes.

Include identity_type required by Pyrax 1.4

Remove a trailing quote

validate files: fix usage error in example tasks

visudo requires the -f option to check any other file than the default.
I've added this to the example ansible tasks.

ec2 inventory plugin: fix whitespace around connection validity test

add_host should not be a changed action

The action doesn't actually change anything on a system, so setting
the status to changed is wrong. add_host is much like set_fact in that
regard.

Since changed is False by default, there is no need to explicity set
it, so just create an empty dict for result and add to it from there.

Add a new module for managing entries in an htpasswd file, used
for basic authentication with web servers such as Apache and Nginx

rhn_register - Correctly load up2date configuration

Previously, a configuration file name of None was being passed into
up2dateInitConfig().  This resulted in a correct configuration import,
but failed to properly save the configuration back to disk in the event
a different serverURL was supplied.  This change removes support for
customizing the up2date filename entirely, and relies on up2date to
choose the default config filename.

Doc: rabbitmq_user pw change and force

Handle login shell bash processes hence match $0 with "*bash"

Document that need to add force=yes to change password of
existing user

fix wrong argument_spec in digital_ocean module

ansible.constants was calling expanduser (by way of shell_expand_path)
on the entire configured value for the library and *_plugins
configuration values, but these values have always been interpreted as
multiple directories separated by os.pathsep.  Thus, if you supplied
multiple directories for one of these values, typically only the first
(at least on *nix) would have e.g. "~" expanded to HOME.

Now PluginLoader does expansion on each individual path in each of
these variables.

as 'required' and 'default' are mutually exclusive removed 'required' in preference of 'default'

Update ansible.cfg

Updated the example ansible.cfg to be more consistent in spacing/commented lines

remote_user should not be set in example config. This file is used in rpm .spec for /etc/ansible/ansible.cfg
