Install cloudooo from git mainstream (like erp5) instead rely on
eggs for this. This makes development and testing faster by adoptiong
mainstream always.

Unify the standalone setup and the setup into erp5 to provide the same
outcome and reduce maintenace.

Update cloudooo configuration to make it compatible with erp5testnode and
permit re-enable continuous integration.

env-PATH is required for use imagemagick, ffmpeg from the instance itself,
and also important to make the tests works.

The slapos default configuration decision:
- text/html does not have Last-Modified
  Because we can not calculate proper last-modified date when the page consists
  of several parts. (e.g.: Gadgets)
- resouces have 'Cache-Control: public'
  Because several versions of Firefox request 'public' to cache resources
  over SSL.
So web_checker.cfg respects the slapos default configuration decision.

No local commit is supposed to exist.

It's necessary on some platforms so it doesn't find the system zlib, even though it doesn't depend on zlib directly.

It's not necessary and was finding system X11 libraries it shouldn't touch.

update md5sum of clarified patch

Seems like old compilers need some help with indirect dependencies of libraries.

We need to remove the BOM because old compilers choke on it (ex.: gcc 4.3.4)

tesseract-eng-traineddata now does all the work

Remove deleted part from erp5 stack as well

Fix broken autoconf invocation

Use a trained data tarbal containing the correct datarootdir structure and the English data.

Instead of using the provided script. Otherwise it'll desperately try to use libtool and its autoconf macros from the system.

Requiring leptonica webp and giflib

This enables ctypes to find the slapos libmagic, instead of the system one

    Make it more versatile.
    - Cache-Control:public,max-age= is also a valid configuration.
    - application/font resources do not need to care about Vary header.

Like this testSpellChecking will stop using the aspell coming from
operating system and wich does not always comes with appropriate
dictionaries

Keep accessing software-url early, in case it was originally done to fail
before trying to connect if this mandatory parameter is missing.

Those sections already exist in extended instance-zope.cfg .

We are never supposed to merge anything. We are supposed to just follow
upstream. pull merges, so it's just the wrong tool.
Instead, fetch and reset.
It is not a problem to always reset, as user already cannot rely on
repository's survival across updates: if there is any error reported by
git command, the repository will be wiped out. So resetting will not do
any more harm than what can already happen.
Also, properly quote paths to protect against spaces (in both command and
update-command).
