Tweak formatting.

Moved *jina* to *jinja2*

Jinja extensions adds features to the jinja2 templating engine. This
patch allows module loading for the templating engine vian an
ansible.cfg configuration key (jinja_extensions).
The default behaviour doesn't change (no module loading).
Requested modules can be added coma separated in ansible.cfg

Adds whitespace handling in jinja_extension config

Added whitespace handling in jinja_extension configuration directive, so
things stay safe if user adds spaces around comas in the directives
list.

Adds config example for jinja_extensions

Added config example with multiple extentions for jinja_extensions

Solving bug : sysctl check_after failing on multi-value sysctl parameters

Documentation fix for apt module: install-recommends

visible on line 121

A collegue of mine has added basix AIX support to the setup, user and group modules.

We have tested this on AIX 5.3 and 6.1 and it works "as advertised"

a colon, which needs some special attention.

See github issue 2702

Add example of read-write git checkout via ssh

If it is a directory, change the destination path by appending the
basename of the source file, like is done if the destination ends with a
/, and try to get the MD5 of the new path.

Fixes #2064.

Remove lots of re use that really shouldn't have been re in the first
place. Initialize pcidata even if lspci is unavailable, and check for
its usability before trying to use it.

Fixes #2060.
