Upstream changes:
-----------------

[Bug] #806: Force strings given to getpass during password prompts to be
ASCII, to prevent issues on some platforms when Unicode is encountered.
Thanks to Alex Louden for the patch.

[Feature] #805: Update shell_env to play nice with Windows (7, at least)
systems. Thanks to Fernando Macedo for the patch.

[Bug] #654: Parallel runs whose sum total of returned data was large
(e.g. large return values from the task, or simply a large number of hosts
in the host list) were causing frustrating hangs. This has been fixed.

[Bug] #791: Cast reboot`s wait parameter to a numeric type in case the
caller submitted a string by mistake. Thanks to Thomas Schreiber for the
patch.
