from repozo doc:

> If a full backup is created, remove any prior full or incremental
> backup files (and associated metadata files) from the repository
> directory.

This solves a problem that after a pack some old repozo files were left
around, with this option they are automatically removed.

Products.TIDStorage was not ported to python3 and is not installed on
software-py3.cfg but the backup crontab expects tidstorage to be
present - as a result, it was silently failing to produce backups.

This brings minimal support to repozo backups on python3, without
Products.TIDStorage interraction and also extends software release test
to have a simple test checking that backups are produced and can be
restored.

Such status file is not created (apparently never was)

GDAL is a component used for a particular client and without a
corresponding software release, so its compilation was not being tested
in SlapOS software release tests.

This commit adds GDAL to the list of tested software, so that it is not
broken by accident.

See merge request !1586.

Bumped both zc.buildout and zc.recipe.egg to keep them in sync.

See merge request !1586.

The upgrade is done to version 3.2.3, as this is the last version which
still supports Python 2.

This fixes the following compilation bug:

```c
gdalwmsdataset.cpp:383:37: error: ISO C++ forbids comparison between
pointer and integer [-fpermissive]
	if(pszHttpZeroBlockCodes == '\0') {
```

Jasper is no longer a dependency, and openjpeg is used instead.

See merge request nexedi/slapos!1586.

OpenJPEG provides a JPEG 2000 codec for use in GDAL.
This was previously provided by Jasper, but support for Jasper is
removed in recent GDAL versions.

See merge request !1586.

Most recent versions of GDAL require this functionality (and it does
not hurt in any case).

See merge request !1586.

Renamed proj4 to proj, to use current naming of the project.
Upgrades PROJ to the last available version (9.4.0) as a previous
step to upgrade GDAL, which depends on it.

See merge request nexedi/slapos!1586.

Upgrades GEOS to the last available version (3.12.2) as a previous
step to upgrade GDAL, which depends on it.

See merge request nexedi/slapos!1586.

THis is a fixup of 4df39d83.

Also copy generated binary to buildout root's bin folder.

* rename enb-output.log to enb-info.log
* add host ID, FPGA version and kernel version in enb-info.log
* keep the 50 latest enb radio logs
* don't let enb-info execeed 500kB, but store up to 100MB of enb-info
