gtk interface building resulted in no gtk interface being built for some
reason, and reference working set ups all used qt, so this commit
switches interface to qt and fights with bugs that come from this
change.

QGtkStyle (needed for Proview-R) support in qt4 needs glib.
However, config script for qt4 is written in such a way that if glib is not
requested but QGtkStyle is requested, it just silently turns QGtkStyle off.

On the other hand, if glib is requested explicitly, then if script fails to
enable QGtkStyle it reports an error properly.
I think it was a bug in qt4 error reporting mechanism that made compilation go
smoothly even though requested QGtkStyle was never provided.
Nobody will fix it now though.

Anyway, this commit properly enables glib and fights with everything that rises
up as a result of this, leading to successfull QGtkStyle support.

https:// link just works more reliably as I found after several timeouts.

But I still have no idea why the second db folder spawns right inside
the frst one.

straighetend the configs:
no more custom source packages
using xvfb for proview compilation (easier)
fix bug with pwr pre-build process killing itself

This script everything required to release slapos.cookbook, and verbose additional information to
the user review and push the changes.

This script automatically slapos.cookbook version on update stack/slapos.cfg also, if you want only
release the EGG w/o using it, you can call it using:

 EGG_ONLY=Y bash release-cookbook

else, call it only by 'bash release-cookbook'.

  This script should be invoked to release a new software release, it will use what is in 1.0 branch to create
  the tag, and it will verbose the follow information...

###################################################################
You are about to release a new version of SlapOS Software Release
Lastest release: 1.0.144
Next Release to be Tagged: 1.0.145
###################################################################
 Please review current tag and them push it:

Update Thiea to 1.0, described a bit on :
 https://dev.to/svenefftinge/theia-1-0-finally-a-good-browser-ide-3ok0

Add by default some extensions for python and buildout. Also request a frontend so that we can access over IPv4

As we have runners with a section deployed using
collective.recipe.shelloutput, if collective.recipe.shelloutput isn't in
the SR folder anymore thisi section can't be uninstalled (as the
uninstall method is defined in the egg).

The output of buildout for this error was :

While:
  Installing.
  Uninstalling runner-sshkeys-publickey-fingerprint-shelloutput.
  Installing recipe collective.recipe.shelloutput.
  Getting distribution for 'collective.recipe.shelloutput'.
Error: We don't have a distribution for collective.recipe.shelloutput
and can't install one in offline (no-install) mode.
While:
  Installing switch_softwaretype.

Starting from nexedi/slapos.recipe.build@5e95d882 gitclone should have built-in support for submodules. Credit: Kirill.

The error was :

 Error: The following paths are already installed by other sections:

There was a typo and anyway it wouldn't have worked because of
nexedi/slapos.buildout!11

Mostly useful for components that are built with cmake.

c++ already exists. cmake searches for c++ in the same folder as it found cc.

Another part wrote to etc/service/frontend_apache, which resulted of
impossibility to start apache after instance is restarted.

The issue is that the upstream package has been bworked (it is not
a .tar.gz in reality), which explains why the md5sum changed).

The source code is also available on github, but with a 3rd md5sum.

This reverts commit 2f705697.
