Jouni Malinen 9308d0a039 tests: Add initial cfg80211 test
This adds some helper definitions and functions to allow cfg80211 to be
tested with raw nl80211 messages built in the test scripts. The first
test case shows a case where station disassociates instead of
deauthenticates (which is the wpa_supplicant behavior).
