Version "name" of installer and snap is now deduced from beremiz' version.py

Beremiz revision bump

GH CD: chechout all projects, even self from prep_sources.yml so that revisions.txt is not too old for Makefile.

revisions.txt is expected in $CWD When building Windows installer, in $CWD/sources for Snap. Deal with it for now.

GH CD: Seriously ? https://github.com/actions/upload-artifact#maintaining-file-permissions-and-case-sensitive-files

GH CD: seems that reusable workflow outputs can't make their way through.

GH CD: place revisions.txt so that snapcraft can find it.

re-starting xvfb-run too fast makes problems. Trying with -a

GH CD: fix artifact decompaction path

GH CD: try to see content of workdir.

Beremiz revision bump

GH CD: Merge sources and snap dir instead of just giving checkout and artfifact download the same path

Update README.md

GH CD: attempt to preserve content of build/source by swapping checkout and artifact download steps.

Fix generation of revisions.txt in makefile

SNAP: replace lxml versions to be compatible with Beremiz.

Forcing ubuntu20 python-lxml (4.5.0) package instead of PIP vesrion (4.9.1).
4.9.1 leads to derived variable types to appear as "derived" instead of real type name.
Problem happens with plcopen/variables_infos.ysl2 and plcopen/VariableInfoCollector.py.
No clue for now about what really breaks.

Beremiz revision bump

GH CD: Add Modbus and open62541 sources.

Add new sanity checksums.

SNAP: add Modbus source and dependencies

SNAP: add SVGHMI and OPC-UA dependencies

Add (untested) snapcraft workflow for GitHub action. Add documentation about manual snapcraft invokation.

Add Snap Package.

For now :
- using makefile :
$ cd ~/build; make -f ~/src/beremiz_public_dist/Makefile DIST=snap
- build and run of python exemple was tested
- no fieldbus support yet.

GH Actions: Add caching for Docker image

GH echo seems to let -e argument through. Trying to force core-utils' echo.

GH Action workflow: more acurate makefile target touching

Rename CanFestival-3 repo into canfestival. CamelCase and '-' in repo name are silly.

Fix syntax errors in build_bundles.yml

Github Action Workflow : desperate attempt to pass environment variable.

merge

Add GitHub Actions workflow file to build windows bundles on push to default branch.

Makefile: Allow overriding revisions IDs through environment, to make it possible to build code comming from non HG repos.

Don't require TTY for docker.

windows installer: force CanFestival build to use source code already checked out rather than re-doing it in anotrher directory.

Add md5 sums forgotten in earlier commit

Dockerfile: use script rather than alias so that bash doesn't need to be interactive shell with a TTY

Use pypi's zeroconf-py2compat instead of zeroconf2. Latest available release is more recent.

Re-enable lzma compression for windows installer

Bundle in installer only fraction of MSYS2: Mingw32. The rest isn't needed for now.
