This changes all tests to use the default get_ordered_network behavior
rather than some custom or incorrect logic. Any use of
scan_if_needed=True has been removed since this is now the default.
Also any explicit scanning has been removed for tests which do not
require it (where the default behavior is good enough).
After the test-runner re-write many tests were left with
stale options that are no longer used at all. These were
periodically getting removed as changes were made to
individual tests, but its apparent now that a tree wide
removal was needed.
Many tests waited on the network object 'connected' property after
issuing a Connect command. This is not correct as 'connected' is
set quite early in the connection process. The correct way of doing
this is waiting for the device state to change to connected.
This common code was replaced, hopefully putting to rest any random
failures that happen occasionally.
At some point a stray ';' got added into an autotest in a section
of code that is heavily copy pasted. So in turn nearly all the autotests
have this stray ';' after list_devices (and a few in other places).
testWPA was not verifying connectivity between the two interfaces. Funny
enough, doing this resulted in the same problems that adhoc had where
we were setting the connection as complete before the gtk/igtk were set.
This is fixed now so we can now use testutil in this test.
