Remove leftover debug statement in template code.

Flush handlers before pre and post task sections change, but not between task and roles, as this seems

Improve variable smushing so it only has to be done in one place.   This is related to shlex.split being called
on untemplated variables in some rare cases.

systemd journal will throw IOError exception when journal.sendv() fails.
This catches that and falls back to syslog.  See issue #2773.

Corrected instance password data check.  Previously broken after adding ...

also link check mode to --simulate option when installing a pkg

fixes #2763

Conflicts:
	library/setup

Documentation: Mention vars_files before the Roles section in playbooks1 chapter

New module 'set_fact' to define host facts

apt module: part rewrite of the upgrade logic

URI module -- make it support HTTP 301, 302, 303, 304, 307

While here factor out password prompting in ansible.utils

Added 'validate' feature to copy and template modules,

If sudoing and the sudo user is not root, the original file is saved as you, therefore delete that file as you.

Allow args: var to be used to pass a variable in bare, and also templated versions should also DWIM.
