concern during tests.

Fix task description

Removed duplicate entries (1.6.1-1.6.3) in changelog.

Related to #7777

In this function, 'site' may be None, which will cause an exception
if it is passed to pipes.quote().

This adds a note to the openbsd-pkg module which explains how to specify
package flavors as well as how to avoid ambiguity errors on a package
with multiple flavors.

Technically, this is not Ansible-specific, but it's pretty likely the
user will encounter this problem.

Previously, the get_fqdn() function in known_hosts.py only worked
with urls that started with git@, and ignored any urls that started
with a normal schema type (ie. http:// or ssh://). This patch corrects
that by using urlparse to parse the hostname portion out of urls that
have a proper schema.
