Upgrade to 0.12.0.

Update provided by Andreas Wrede <andreas@planix.com> via PR pkg/23319.

Changes:

031023	Released 0.12.0.

	Penlogd: sscanf would read 100 bytes + terminating nul into
	a buffer of size 100. Now reads 99+nul. Spotted by Oezguer Kesim.

	Let tracking time be set through penctl.cgi.
	In do_cmd, "no log": only close the logfile if it is open.
	New penctl command, "write [FILE]" writes current configuration
	to a file. If FILE is omitted, overwrite the original
	configuration file (-F option).

	Pen: Time based expiration of tracked clients. Default is
	0 seconds = never expire. Added -T option to control expiry
	time. Also added penctl command "tracking N".
	Penlogd: zero-terminate results from recvfrom.

	In penlogd.c: don't complain if recvfrom is interrupted by signal.

More bugfixes, etc.
