Avoid creating needless entries and minimise needless newlines, and reflect
this in test data, as in such case no backend_log is created, as nothing is
configured on backend Haproxy level.

SSL cache is unusable in context of caddy, same for the so called HTTPD home.
Those are old Apache leftovers.

It's a dict, and in SlapOS usage of Jinja2 it's good to see the type of
a variable immediately.

"parameter_dict" says nothing, whereas "software_parameter_dict" explains
source and purpose of the information.

There is needless duplication of information.

That's true, that those are templates, but the important information which
shall be in the name of the parameter is its purpose - a profile.

Section template-apache-frontend was not updated in buildout.hash.cfg

development.cfg is never used, and having split software definition in
software.cfg and common.cfg just makes development harder.

This reverts commit 1c2d1c0a.
because NEO is not ready for such change.

nbd-host and nbd-port is not required in case of simplified configuration, use
boot-image-url-select instead.

5.2.2 brings in important fix that is needed for wendelin.core 2:

They say that `zodbpickle.binary` is now much more lightweight on CPython2:
https://github.com/zopefoundation/zodbpickle/blob/master/CHANGES.rst#200-2019-11-13

software/caddy-frontend implements all requirements and apache-frontend is
not tested neither developed except small fixes, so it's ok to keep it for
reference or some small work outside of official tree, as other developers
might have urge to use it.

*  Updates component/pureftpd url to 1.0.49 version because the one provided do not exist anymore (the 1.0.46 version exists now under the path [https://download.pureftpd.org/pub/pure-ftpd/releases/obsolete/pure-ftpd-1.0.46.tar.bz2](https://download.pureftpd.org/pub/pure-ftpd/releases/obsolete/pure-ftpd-1.0.46.tar.bz2))
*  Deletes explicit slapos.toolbox dependency because it's automatically installed by monitor stack

See merge request nexedi/slapos!834

* syntax highlighting for git commit message and git rebase
* include a slapos logo
* Include some better monospace fonts (Source Code Pro and Jetbrains Mono)

This reverts commit 3d12ddae.

The commit was instroducing errors in compilation or at runtime.

Compilation error were like (for cmake in Debian 8 machine):
[ 99%] Built target CTestLib
[100%] Built target ctest
Install the project...
bin/cmake: /usr/lib/x86_64-linux-gnu/libstdc++.so.6: version `GLIBCXX_3.4.21' not found (required by bin/cmake)

cmake: Compilation error. The package is left as is at /srv/slapgrid/slappart61/srv/runner/shared/cmake/9fc4b0e8f4f03ce17eb7ef43525d2238__compile__/cmake-3.7.2 where you can inspect what went wrong.

Runtime errors were like (for mariadb in Debian 9):

Be nice test and clean up your own mess.

~/bin/slapos script does not overwrite $SLAPOS_CONFIGURATION if it's set,
to prevent service accidentally use another slapos.cfg if $SLAPOS_CONFIGURATION
is set for some reason, explicit pass the path of the slapos.cfg

This solves vulnerabilities reported by npm upon installation.

We'd prefer ld to always take LD_RUN_PATH into account, even if any
rpath is specified in the command-line. We could actually change the
wrapper this way but it would not be consistent with the case where
the SR is built with system gcc.
