Add NetBSD icons to share/nagios/images/logos/, for the benefit of
web interface (especially the map), using an extra distfile in
MASTER_SITE_LOCAL
bump PKGREVISION
Updated net/nagios-base to 3.4.3nb5
Updated devel/lua-lpeg to 0.12.
Update data in lua-lpeg entry.
Not MAKE_JOBS_SAFE; I got
OSError: [Errno 2] No such file or directory: '[...]/work/.home/.cache/g-ir-scanner/058d13a6d877030b8adb448928d5630d364836c5'
with 8 jobs on try 1; try 2 without changes succeeded.

This probably applies to the whole plugin framework and should go in
Makefile.common, but let's be conservative about it.
Also used right here in River City.
Fix previous, part of the patch was rejected and I dind't notice.
Fix nagios-base entry
Add a note about qemu version, pointing to the man page.
