Given user report that EL5 sudo does not support '--', remove it, and things seem to still work fine.

let me know if this breaks any other boxes.

Update file module to not recurse when setting ownership

Fixes for raw module usage and failure to open_session()

Bugfix/pip2

Signed-off-by: Sebastien Bocahu <sebastien@ispfr.net>

This updates set_owner_if_different() and set_group_if_different()
to not implicitly recurse when setting ownership (whether user or
group).  It drops the os.system() call and replaces it with os.chown().
Resolves issue #825.

The recursion should be explicit.  A recurse=yes|no option should be
added to the file module.

Ran across non-unix host where the call to paramiko's open_session() in
exec_command() would throw a EOFError exception.  This change wraps the
block in a try/except.

runner should not try to create or remove tmp paths when using the raw
module.

Relative symlinks don't really work (module bug) and would be confusing anyway, better to be explicit.

make yum module work with list=pkgspec

It is still required to use list=..., but the typical install and remove
won't need it.

Update man pages and the message for an exception.
