This caused that the xz command was called without any
extra arguments. This will now create the tar archive
first and then pass the archive through xz with our
command line switches.

'ipfire-2.19.i586-full-core121.iso' => 207 MB
Total => 753 MB (-39 MB)
It would be nice if someone could review and test these. ;-)
If necessary, I can upload a complete patch.

Hi,
as mentioned in the "list", we're trying to make the archives as small as possible
using 'xz'-compression.
In order to achieve this, this patch tests the size of the memory available on the
host system.
It sets the xz-memory-limit (--memory=[N]Mib) to 70% of the available working memory,
a maximum of four xz-'worker threads' (-T4) and a compression rate of '-8' (-8).
These options are written to the 'XZ_OPT=' environment.
For details see:
https://linux.die.net/man/1/xz
I have set the number of available xz-'worker threads' (-T) to four (-T4), because during
the final tests the '-T0' parameter led to error messages snd stopped: 'cannot allocate memory'.
It wouldn't even run with 90%.
Furthermore, testing with '-T0' led to countless messages filling up '_build.packages.log'.
E.g.:
...
xz: Adjusted the number of threads from 8 to 2 to not exceed the memory usage
limit of 1557 MiB
...
Tests took place on a 32bit-Ubuntu 16.04.4-system with 8 GB RAM and an Intel I7-2600.
Build time was about 04:30 hrs. Perhaps a 64bit-system would perform better (higher
values), but my goal was to make this run on as many systems as possible, so I choosed
these averages.
If minimum requirements (1024 MB RAM) are not met, building stops.
Current results:
'next', untuned:
ipfire-2.19.2gb-ext4.i586-full-core121.img.gz => 332951687 Bytes
ipfire-2.19.i586-full-core121.iso => 228589568 Bytes
'next', XZ_OPT: -T4 -8, 70% RAM:
ipfire-2.19.2gb-ext4.i586-full-core121.img.gz => 329725723 Bytes
ipfire-2.19.i586-full-core121.iso => 217055232 Bytes
These two resulting archives are 14760300 Bytes smaller than before.
Best,
Matthias

Install initscript for NRPE addon.
The second version of this patch actually includes the
initscript, which was missing due to lack of coffee the
first time. :-)
Thanks to Michael for catching it.
Resent due to crappy linewrapping in initscript by MUA.

Update NRPE to 3.2.1, which fixes various security vulnerabilities
and bugs (changelog is available at:
https://github.com/NagiosEnterprises/nrpe/blob/master/CHANGELOG.md).
Due to changes in ./configure, some options such as initsystem (sysV)
need to be specified now. Also, simple "make" does not exist anymore
and must be replaced by "make all".
Rootfile information is now included which was missing in the
first version of this patch.
This fixes#11700 and partly addresses #11551.

Update ClamAV to 0.100.0, which brings some new features and bugfixes
(release notes are available here: https://blog.clamav.net/2018/04/clamav-01000-has-been-released.html).
Since the internal LLVM code is now deprecated and disabled by default,
patching clamav/libclamav/c++/llvm/lib/ExecutionEngine/JIT/Intercept.cpp
does not seem to be necessary anymore.
Further, the --disable-zlib-vcheck option has been removed since it
produces warnings during compilation.
