pcap_next_ex() will allow us to detect the end of a capture file. Since
we used pcap_loop() to capture one packet at a time anyway, this won't
change anything for live captures.
The variable names were standardised in functions using pcap data types
('pkt_header' and 'pkt_data' instead of 'header' and 'packet').
Aggregation time, check intervals, etc.
By default the aggregator cannot fully aggregate calibration requests
any more, only the positioning and autocalibration requests.
In order to aggregate calibration requests, the aggregation timeout
needs to be increased, or the number of packets of the request and
the delay between each of them lowered.
Differentiate the port on which the autocalibration hello messages are
sent to the aggregator by the listeners, and the one on which the
autocalibration orders are sent by the aggregator to the listeners.
This will allow to run a listener and an aggregator on the same machine
with autocalibration enabled.
Both in the listener and the aggregator, the option -a (autocalibration
port) has been replaced by the options -O (autocalibration order port)
and -H (autocalibration hello port). In the listener, the option -H was
previously used to set the hello delay; this is now the role of the -T
option.
Add the compile-time option ENABLE_KEEP_MONITOR to enable/disable the
option -K. That allows to make optional the dependency on iwlib.
This option is disabled by default in the Makefiles.
The configuration parsing function could call exit() (e.g. with -h, -V,
or in case of error), implying a memory leak. This is fixed.
Additionally, minor cleaning in the configuration functions.
The <endian.h> header is Glibc-specific. On BSD platforms, one have to
use <sys/endian.h>.
(This was the occasion to improve the preprocessor code here.)
In capture(), the pcap_loop() call was blocking, so the program did not
quit if no packet came on rtap_iface. This is now fixed by a call to
pcap_breakloop() in the signal handlers.
