Remove tests that involve network effects -- makes things faster and they are not really deep tests here either way.

Various retooling of the internal code behind inventory pattern matching in support of pending support
for host ranges.

add the limit option, which can be used to further confine the patterns selected by "hosts:" in ansible-playbooks
to an additional pattern (a subset) specified on the command line.  For instance, a playbook could be reusable
and target "webservers" and "dbservers", but you want to test only in the stage environment, or a few boxes at a time.

Add ability to store and access module results later on in the play.  See examples/playbooks/register_logic for details.

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.
