Fixes #1516.

Keep hostvars from being templated

Use all available vars for hosts:, user: and sudo_user:

Print the task name (if any) when complaining

Make parameterized playbook includes work with vars as a list

After spending 10 minutes to find which playbook had an action/local_action missing, I changed the error to include the task name (if set). The error eventually was caused because I added a name to a task, but the dash before the existing action was not removed.

Fixes #1610.

Try to ensure the entire value is quoted

add bsd md5 support to fetch module

Templating fixes and features

minor linux user module fixups

Previously, "a $ string $var" would not have gotten replaced at all.

Template using module_vars early

Since no basedir is available at that time, avoid invoking
lookup plugins since they assume it is present.

moduleformatter.py should include our own ansible clone

Without this, module_formatter.py relies on the installed ansible which is wrong in more than one way.

Add parameterized playbook includes

Add support for generic $XXX() to call $LOOKUP()

Add ability to specify syslog facility for modules

ansible-playbook verifies playbooks exist before running them

remove verbose option on digest call

refers to #1345

Add --limit to calls to ansible and ansible-playbook

Update constants.py so that one can specify environmental variable
ANSIBLE_SYSLOG_FACILITY or syslog_facility in ansible.cfg to define
the syslog facility to use.  Alternatively, you can specify
ansible_syslog_facility in inventory.  Runner now replaces
the syslog facility in the openlog() call with the default or
the injected variables ansible_syslog_facility.

This also updates hacking/test-module to behave similarly.

--limit takes localhost, FQDN, and 127.0.0.1.
