It was possible for a registered eloop socket handler to be unregistered
and re-registered for a re-opened socket with the same fd from a timeout
or signal handler. If such a case happened with the old socket having a
pending event waiting for processing, some eloop combinations could end
up calling the new handler function with the new socket and get stuck
waiting for an event that has not yet happened on the new socket. This
happened with timeout and signal handlers with all eloop.c types. In
addition to that, the epoll case could also trigger this when a socket
handler re-registered a re-opened socket.
Fix these by checking whether there has been socket handler changes
during processing and break the processing round by going back to
select/poll/epoll for an updated result if any changes are done during
the eloop handler calls before processing the old socket results.

Try to exit more quickly by avoiding execution of the action script for
any pending events if the process is requested to be killed. This may
help in avoiding hitting the two second SIGALRM workaround in eloop in
case some of the action scripts block for long period of time.

It was possible for the SIGINT/SIGTERM signal to be received while
processing a pending timeout/socket/signal event and then get stuck in
the following select() call before processing the signal event. If no
other events show up within the two second SIGALRM trigger, process will
be terminated forcefully even though there would have been possibility
to do clean termination assuming no operationg blocked for that two
second time.
Handle this more cleanly by checking for eloop.pending_terminate before
starting the select()/poll()/epoll_wait() wait for the following event.
Terminate the loop if pending signal handling requests termination.
In addition, make eloop_terminated() return 1 on eloop.pending_terminate
in addition to eloop.terminate since the process will be terminated
shortly and there is no point in starting additional processing.

The functions parsing configuration parameters do not modify the name of
the parameter, so mark that function argument constant. In theory, the
value should also be const, but at least for now, number of the parser
functions end up modifying this to simplify parsing.

This adds a new global control interface command DUP_NETWORK with the
following syntax:
DUP_NETWORK src_ifname dst_ifname param
The currently supported parameters:
wpa
wpa_key_mgmt
wpa_pairwise
rsn_pairwise
wpa_passphrase
wpa_psk
The specified configuration parameter is copied from the source
interface to the destination interface. The main use for this is to
allow cloning of security configuration without having to expose the
keys from the hostapd process.

This header file is needed to get struct fst_iface_cfg and struct
fst_wpa_obj defined. While it does currently get pulled in through
ap/hostapd.h and ap/ap_config.h, a more explicit inclusion may be a
cleaner option for future.

This new mechanism can be used to combine multiple periodic AP
(including P2P GO) task into a single eloop timeout to minimize number
of wakeups for the process. hostapd gets its own periodic caller and
wpa_supplicant uses the previously added timer to trigger these calls.

Previously, one timeout per process (by default every 30 seconds) was
used P2P peer expiration and another per-interface timeout (every 10
seconds) was used to expire BSS entries. Merge these to a single
per-process timeout that triggers every 10 seconds to minimize number of
process wakeups due to periodic operations.

For some reason, snprintf() was not seen as sufficient to remove
potentially tainted string from fgets() before passing this to rename().
This does not make much sense, but anyway, try to get rid of the warning
by using a separate buffer for the internally written file names.
