7ffe7d222a AP: Use monotonic time for MMIC failure/TKIP countermeasures
Wall time jumps shouldn't affect MMIC failure/TKIP countermeasures,
so use monotonic time. Change the michael_mic_failure variable to
struct os_reltime for type-safety.

c772d054c2 hostapd: Fix a regression in TKIP countermeasures processing
Commit 296a34f0c1 changed hostapd to
remove the internal STA entry at the beginning of TKIP countermeasures.
However, this did not take into account the case where this is triggered
by an EAPOL-Key error report from a station. In such a case, WPA
authenticator state machine may continue processing after having
processed the error report. This could result in use of freed memory.
Fix this by stopping WPA processing if the STA entry got removed.

296a34f0c1 Remove STA entry from AP when starting TKIP countermeasures
Previously, the STA entry was removed only from the driver and the STA
entry within hostapd was just marked disassociated. However, this left
the WPA authenticator state machine with an entry and the session was
not terminated properly. In addition, the STA entry could have remaining
indefinitely if the STA did not reconnect after TKIP countermeasures.
Fix this by removing the STA entry from hostapd instead of just leaving
it disassociated.

01a1749156 Fix TKIP countermeasures stopping in deinit paths
The eloop timeout to stop TKIP countermeasures has to be canceled
on deinit path to avoid leaving bogus timeouts behind.

6905dcb1e0 AP: Introduce sta authorized wrappers
To enable making state change notifications on the WLAN_STA_AUTHORIZED
flag, introduce ap_sta_set_authorized(), and to reduce use of the flag
itself also add a wrapper for testing the flag: ap_sta_is_authorized().

6226e38d00 Rename some src/ap files to avoid duplicate file names
Doxygen and some build tools may get a bit confused about same file
name being used in different directories. Clean this up a bit by
renaming some of the duplicated file names in src/ap.

1057d78eb8 Move generic AP functionality implementation into src/ap
This code can be shared by both hostapd and wpa_supplicant and this
is an initial step in getting the generic code moved to be under the
src directories. Couple of generic files still remain under the
hostapd directory due to direct dependencies to files there. Once the
dependencies have been removed, they will also be moved to the src/ap
directory to allow wpa_supplicant to be built without requiring anything
from the hostapd directory.
