broke adding extra IEs in sched scan. The IEs stopped being added

GAS_QUERY_TIMEOUT value was used for two different things - enum for
status callback and #define for internal eloop timeout). The latter
overwrites the former and as such, the timeout reported ended up going
out with value 5 which matches with GAS_QUERY_CANCELLED instead of
GAS_QUERY_TIMEOUT. This value was not used in existing code, so this
should not modify the current behavior. Anyway, the correct reason for
the failure should be reported. Rename the internal #define for the
timeout period to avoid the name conflict. [Bug 463]

This function can be used as a wrapper for os_realloc(ptr, nmemb * size)
when a reallocation is used for an array. The main benefit over
os_realloc() is in having an extra check to catch integer overflows in
multiplication. This is similar to the os_zalloc() to os_calloc() move.

There is no need to mandate admission control (ACM=1) by default, so
clear that flag in the case the configuration file does not specify
wmm_ac_{vo,vi}_acm value. This gets closer to the values mentioned
in the sample hostapd.conf file and reduces the need to specify WMM
parameters in the configuration file for most common use cases.

In case of P2P GO and AP mode, wpa_supplicant uses the default hostapd
parameters for WMM. In the default parameters the ACM bit for video and
voice are set to 1, meaning, P2P devices and stations which are
connected to the GO cannot pass voice or video data packets. Allow this
to be changed through wpa_supplicant configuration file with wmm_ac_*
parameters.

p2p_set_timeout() calls in GO Neg Req/Resp TX callbacks used timeout of
100 ms which is the value given in the P2P specification for GO
Negotiation, but this was actually shorter than the
wait-for-offchannel-TX value (200 ms) used for the driver call. In
addition, it looks like some devices (e.g., Galaxy Nexus with JB image)
can take longer time to reply to GO Negotiation Response (somewhere
between 200 and 250 ms has been observed).
Increase the wait-for-GO-Neg-Resp timeout from 100 ms to 200 ms if GO
Negotiation Request frame was acknowledged (this matches with the
offchannel wait timeout that used previously). The no-ack case is left
at 100 ms since we use GO Negotiation Request frame also to discover
whether the peer is on its Listen channel.
Increase the wait-for-GO-Neg-Conf timeout from 100 ms to 250 ms (and
increase the offchannel wait timeout to matching 250 ms) as a workaround
for devices that take over 200 ms to reply to GO Negotiation Response.

This is the normal flow for association:
wpa_supplicant <--(EVENT_ASSOC event )-- device driver
wpa_supplicant --( get_bssid() )--> device driver
wpa_supplicant <--( return BSSID )-- device driver
However, a device driver could return EINVAL for get_bssid() because it
recognizes it has already been disconnected. When the wpa_supplicant
received EINVAL, the bssid field could be used uninitialized in the
following flow:
wpa_supplicant <--(EVENT_ASSOC event )-- device driver
device driver (receive deauth)
wpa_supplicant --( get_bssid() )--> device driver
wpa_supplicant <--( return EINVAL )-- device driver
Prevent this by requiring the get_bssid() call to succeed when
processing association events.

cur_pmksa was left to NULL during the initial association. This can
result in unexpected behavior, e.g., in expiring PMKSA cache entries

If the PMKSA cache is full (i.e., 32 candidates have been seen in scan
results and have not yet expired) then any additional entries can
potentially evict the current/active entry (if it is the oldest entry),
which triggers a pointless local deauthentication. The supplicant
shouldn't replace the current/active entry if it is still valid, but
instead the oldest entry that is *not* the current/active one.

When using multiple VLANs, GKeyDoneStations counter is not updated
properly since wpa_auth_for_each_sta() call in wpa_group_setkeys() ends
up iterating through all STAs and not just the STAs of a specific
wpa_group (VLAN). Consequently, GTK rekeying gets initialized multiple
times if more than a single group state machine exists. Fix this by
iterating only through the STAs in the specific wpa_group.

This enables setting a different max inactivity timeout for P2P GO.
This timeout is used to detect inactive clients. In some scenarios
it may be useful to have control over this and set a shorter timeout
than the default 300s. For example when running STA and P2P GO interfaces
concurrently, the STA interface may perform scans which may cause the
GO to miss a disassoc / deauth frames from a client and keep assuming
that the client is connected until the inactivity detection kicks in.
300 secs is a bit too long for such scenarios and creates a bad user
experience.

Right now 11b rates are masked out while creating a P2P interface,
but this is always failing as the interface is down. Most drivers
allow to configure rates only when the interface is UP and running.
So let us disable 11b rates when interface type is changed into a
P2P type and it is UP and running.
