0fa0ad4e17 eloop: Fix integer overflow in long timeouts
If the os_time_t variable used for the expiration time (seconds)
overflows when the registered timeout value is being added,
assume that the event would happen after an infinite time, i.e.,
would not really happen in practice. This fixes issues with
long key timeouts getting converted to immediate expiration due
to the overflow.

7f5957abcf eloop: Fix crash on signal handler cancelling next timeout
It is possible that the timeout pointer becomes invalid in one of the
signal handlers, so we need to reload the pointer after those.

2e320d8db5 eloop: Clear timeout data during allocation
Better make sure the eloop_timeout data gets fully initialized. The
current code is filling in all the fields, but it is clearer to just
zero the buffer to make sure any new field added to the structure gets
initialized.

459489c99d eloop: Fix timeout handler to use local copy of func pointer
We need to copy not only the context pointers, but also the function
pointer before the timeout gets freed.

9aca440199 Drop WPA_TRACE reference before eloop timeout handler call
This avoids bogus error reports for cases where the timeout handler
frees the memory that was pointed to by the eloop timeout context.

a6ff0e0810 trace: Add active reference tracking
This WPA_TRACE=y additions allows components to register active references
to memory that has been provided to them as a pointer. If such an actively
referenced memory area is freed, tracer will report this as an error and
backtraces of both the invalid free and the location where this pointer
was marked referenced are shown.

0456ea16d8 eloop: Remove global user data pointer
This is not really needed since all signal handlers can use a context
pointer provided during signal handler registration.

930f704aac Add backtrace support for debugging
WPA_TRACE=y can now be used to enable internal backtrace support that
will provide more details about implementation errors, e.g., when some
resources are not released correctly. In addition, this will print out
a backtrace automatically if SIGSEGV is received.

7e1488494e Do not continually reschedule specific scans to help finding hidden SSIDs
In situations where the driver does background scanning and sends a
steady stream of scan results, wpa_supplicant would continually
reschedule the scan.  This resulted in specific SSID scans never
happening for a hidden AP, and the supplicant never connecting to the AP
because it never got found.  Instead, if there's an already scheduled
scan, and a request comes in to reschedule it, and there are enabled
scan_ssid=1 network blocks, let the scan happen anyway so the hidden
SSID has a chance to be found.

registering an eloop timeout.
