remove useless create/delete remote tmp dir roundtrip in copy module

Make sure 'tmp' is in the remote tmp dirname to ensure correct cleanup

Improved the documentation for password generation

Remove testing code

I guess this is left over from testing

Retroactively added v1.4.4 to CHANGELOG.md that was omitted during release.

rax module: improvements

Adding support for detecting RHEV Hypervisor in ansible_virtualization_type

While looking into filters, I noticed that the documentation has a typo....

Fixes #5513. set is built-in since 2.4 and deprecated since 2.6

Modified docsite layout to use Google custom search.

Synchronize Module: Improved sudo override behaviour.

ec2 modules: Move more responsibility to common EC2 module

file module: Fixed missing prev_state == 'directory' in file

ec2 inventory: Fail EC2 inventory better with restricted EC2 users

Allow multiple users to use ec2 inventory scripts

This may still be an issue if users create roles with a '.' in the name though.
We will probably have to disallow that in the role naming convention.

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

Reverts 564a212b

fix issue #5372 on ssh_alt: accept -K option for a user with NOPASSWD

Use "brew list <name>" instead of grepping the output of "brew list". Fix for #5488

Return early from setup step when possible

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.

Fixed typo in example documentation
