* Strip lookup calls out of inventory variables and clean unsafe data
  returned from lookup plugins (CVE-2014-4966)
* Make sure vars don't insert extra parameters into module args and prevent
  duplicate params from superseding previous params (CVE-2014-4967)

Updates to Makefile include:
 * add targets: deb-src, deb-src-upload, deb-upload
 * add variables to control DEB building: DEBUILD_OPTS, DPUT_OPTS, DEB_PPA, DEB_DIST, DEB_RELEASE
 * create deb files for all release values in DEB_DIST

Several updates to packaging/debian/*
 * Updated control file
 * Whitespace/formatting of changelog

Add deb-build to .gitignore

The os.path.isdir() returns True for symlinks that point to directories,
so we also need to check to make sure it's not a symlink too.

fixing problem where ansible would error out because Amazon was saying the group didnt exist yet (needed to wait a few more seconds for amazon to propagate correctly)

Using sets for these operations is dangerous because sets cannot contain
certain object types (such as lists) and their iteration order is
undefined.

This was causing a bug in the env module, due to the fact that we now
pass variables for the module through the templating engine combined
with the fact that we split-up the hostvars and setup variables. As a
result, if a variable in the env lookup had the same name as the variable
in Ansible, it would try and template itself over and over again until
the recursion limit would be hit, at which time an empty string was
returned.

Fixes #7396

Remove colon which breaks installation of 1.6.2.

Rework the description so that it doesn't require the colon, rather
than just wrapping it in quotes.
