This commit implements hostapd global control interface notifications
infrastructure. hostapd global control interface clients issue
ATTACH/DETACH commands to register and deregister with hostapd
correspondingly - the same way as for any other hostapd/wpa_supplicant
control interface.

The new phase1 config parameter value tls_disable_tlsv1_0=1 can now be
used to disable use of TLSv1.0 for a network configuration. This can be
used to force a newer TLS version to be used. For example,
phase1="tls_disable_tlsv1_0=1 tls_disable_tlsv1_1=1" would indicate that
only TLS v1.2 is accepted.

A typo in wpa_scan_result_compar() caused wrong scan results sorting
(and wrong roaming decision). This fixes a copy-paste regression
introduced by commit a1b790eb9d ('Select
AP based on estimated maximum throughput').

If a device may be an explicit GO, it adds the GO details in the PD
Request. First, we try to reuse an active GO. If it is not present, we
try to reuse a non-active persistent group. In the latter case, if a
dedicated P2P interface is needed, the intended address should be that
of the pending interface. However, the wpas_get_go_info() provided the
ssid->bssid address, which is the address of the P2P device. This might
result in an incorrect intended interface attribute in the PD Request in
case a separate group interface is used.
Fix this by setting group_iface variable to true only if a dedicated
interface should be used and set the attribute accordingly.

If after P2PS PD the device should become a GO it sends P2PS-PROV-DONE
event which contains the GO interface name. If the GO isn't running yet
the device may use pending interface name. However, when the GO is
started, pending interface name will be removed.
Fix the GO interface name in P2PS-PROV-DONE event by copying the
interface name instead of saving the pointer.

The new TEST_FAIL and GET_FAIL control interface commands can be used
similarly to the earlier TEST_ALLOC_FAIL/GET_ALLOC_FAIL design. The new
version is more generic framework allowing any function to be annotated
for failure testing with the TEST_FAIL() macro. This mechanism is only
available in builds with CONFIG_WPA_TRACE_BFD=y and
CONFIG_TESTING_OPTIONS=y. For other builds, the TEST_FAIL() macro is
defined to return 0 to allow the compiler to remove the test code from
normal production builds.
As the first test site, allow os_get_random() to be marked for failing
based on call backtrace.

Do not allow 40 MHz co-ex PRI/SEC switch to force us to change our PRI
channel if we have an existing connection on the selected PRI channel
since doing multi-channel concurrency is likely to cause more harm than
using different PRI/SEC selection in environment with multiple BSSes on
these two channels with mixed 20 MHz or PRI channel selection.

In p2p_find command line processing a loop searching for multiple
'seek=' parameters modifies cmd buffer adding '\0' terminators.
The 'freq=' parameter is handled after that and can be
lost if a 'freq=' follows 'seek=' in a command line.
Fix it by moving a handling of 'freq=' parameter to be processed
before 'seek=' handling loop.

In case of a network interface removal, check if the interface
was also the parent interface of the P2P Device dedicated interface.
If this is the case, then stop the P2P Device functionality, and
remove the P2P Device dedicated interface.
In case that the interface is added again and P2P Device
functionality can be enabled again, add a new P2P Device dedicated
interface and allow further P2P Device functionality.
In case that the P2P Device dedicated interface is re-created, the
original P2P Device configuration file is needed, so store it in
the global params (instead in the wpa_interface configuration).

PBC overlap detection searches for another BSS with active PBC in the
BSS table. However, when a separate P2P interface is used, scan results
without P2P IE are not saved in the BSS table, so non-P2P BSS's with
active PBC will not be detected.
Fix this by iterating only the WPS AP array instead of the BSS table.
This is also more efficient since only WPS APs may have active PBC. This
also fixes hwsim test "grpform_pbc_overlap" when a dedicated P2P Device
is used.
