fix issue #5372 on ssh_alt: accept -K option even for a user with NOPASSWD
Use "brew list <name>" instead of grepping the output of "brew list".

Some brew packages are not listed with their package name, e.g. libjpeg.
Remove code underlying when_* and only_if, which are deprecated features slated for removal in the 1.5 release.
Fixed typo in example documentation
Complete removal/refactoring of conditional deprecations.
Return early from setup step when possible

The _list_available_hosts call can be lengthy, and in the case where
gather_facts is disabled the call is pointless. So re-arrange the logic
to return early from _do_setup_step when gather_facts is false.

Use list comprehensions for efficiency

For loops can be inefficient, particularly when doing a dot command with
them. https://wiki.python.org/moin/PythonSpeed/PerformanceTips#Loops and
https://wiki.python.org/moin/PythonSpeed/PerformanceTips#Avoiding_dots...

This patch makes use of list comprehensions to be as efficient as
possible while still retaining order. Efficiency was lost a bit when
switching away from sets() but this gains some of it back.
Update various copyrights.  Not complete, but sufficient.

Fact gathering on a second play against the same hosts should not be implicitly off since this is an undocumented beheavior and potentially
rather unwanted when a play could change a fact.

gather_facts: True/False can still be explicitly used per play.

Improvements to the rax module

* Support state=absent with group or a group meta key
* Add auto_increment attribute to allow specification of a group without forcing an auto incrementing host number
* Add additional example that showcases exact_count functionality
* Don't use a file handle for files to upload to the server, read in the contents to avoid an issue where the file handle wasn't reset and an empty file was being uploaded
