We can only send module specific messages to syslog and not debug
messages printed with wpa_printf. Add an extra command line parameter
'-s' to allow it. The feature is enabled with compile flag
CONFIG_DEBUG_SYSLOG as for wpa_supplicant and behaves in the same manner
as the wpa_supplicant -s command line argument.

Fix mostly theoretical NULL pointer dereference in
wpa_debug_open_linux_tracing() if /proc/mounts were to return a
malformed line.

wpa_debug_reopen_file() used to write an error message at MSG_ERROR
level if it was called with last_path == NULL (the last debug log file
path not known). This is not a fatal error, but a normal case if
wpa_debug_open_file() has not been used. Remove the error message and
return success in such case.

This makes it possible to use these helper functions from hostapd as
well as the current use in wpa_supplicant.

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.

When hostapd or wpa_supplicant is run in debug more with key material
prints allowed (-K on the command line), it is possible for passwords
and keying material to show up in debug prints. Since some of the debug
cases end up allocating a temporary buffer from the heap for processing
purposes, a copy of such password may remain in heap. Clear these
temporary buffers explicitly to avoid causing issues for hwsim test
cases that verify contents of memory against unexpected keys.

Instead of an int variable with magic values 0, 1, 2, use an enum that
gives clearer meaning to the values now that the original boolean type
global argument is not really a boolean anymore.

If hostapd will use stdout for debugging, set stdout to be line
buffered in case its output is redirected to a file. This allows
incremental output to be viewed immediately instead of at the file
buffering interval.

This change adds a cast to void to indicate that the path parameter is
unused when CONFIG_DEBUG_FILE is not defined. This fixes a compiler
warning about unused parameters.

This is similar to wpa_msg_global() in the same way as wpa_msg_ctrl() is
to wpa_msg(). In other words, wpa_msg_global_ctrl() is used to send
global control interface events without printing them into the debug
log.

These events are sent as a special case to both the group interface and
"parent interface" (i.e., the interface that was used for managing P2P
negotiation). The latter is not really correct event, so get rid of it
with the new global control interface design where there is no need to
support legacy upper layer implementations.

This function can be used instead of wpa_msg() and wpa_msg_ctrl() to
indicate that an event is not specific to a network interface.

Add the option (-T) to wpa_supplicant to log all debug messages into the
kernel tracing, allowing to aggregate kernel debugging with
wpa_supplicant debugging and recording all with trace-cmd.
Since tracing has relatively low overhead and can be filtered
afterwards, record all messages regardless of log level. However, it
will honor the -K option and not record key material by default.

This patch allows to log hexdumps into syslog.
This is useful when testing, as syslog's network logging
helps to collect debug outputs from several machines.

This makes log files much more readable if multiple interfaces
are being controlled by the same process. The interface name is
added to stdout/file/syslog entries, but not to the messages
sent to control interface monitors to avoid issues with parsing
in external programs.

This is like wpa_msg(), but the output is directed only to
ctrl_interface listeners. In other words, the output will not be
shown on stdout or in syslog.
Change scan result reporting to use wpa_msg_ctrl() for
CTRL-EVENT-SCAN-RESULTS message at info level and wpa_printf() at
debug level to avoid showing scan result events in syslog in the
common configuration used with NetworkManager.
