Instead of using an always-different logger name which confuses log
analytics system, use the warning category as logger name (or what zLOG.LOG
calls "subsystem")

Rename this column from "Sale Trade Condition" to "Trade Condition", so
that it can be used also for purchase and internal trade conditions.

Changes following up nexedi/slapos!985

It seems the logo is a bit bigger, or at least a bit different

See merge request nexedi/erp5!1424

When running OCR, we sometimes have issues because processing is "too heavy":
 - [x] use 2 or 3 Go of disk space for a one page PDF created by erp5_document_scanner, because we convert pdf -> png -> tiff before sending to tesseract. Modern Ghostscript supports running tesseract directly, so we use it if it's available.
 - [x] use 300% of CPU. Fixed by setting `OMP_THREAD_LIMIT` when running tesseract. This will only apply when OCR from Images. OCR embedded in Ghostscript does not seem to need this.
 - [x] ... and often crash, so is restarted. This is fixed by updated tesseract.

Updates of ghostscript and tesseract are part of nexedi/slapos!985

This timestamp break officejs offline capabilities.

This reaplies 40f6c8fe ([erp5_xhtml_style] ckeditor: drop hardcoded
timestamp parameter in URL, 2017-10-16) on the updated CKEditor

This was done with:

    find product/ERP5/bootstrap/erp5_xhtml_style/SkinTemplateItem/portal_skins/erp5_ckeditor/ckeditor/ -type f  | xargs sed -i 's/"L4KA"/""/g'

L4KA was the timestamp for this build, that we can in the top of ckeditor.js

By relying on PIL after our monkey-patched OFS.Image.getImageInfo.

We keep this monkey-patch for now, because it adds supports to svg

Since 7f32f8cd (erp5_dms: Add PDF Reader using the pdf.js, 2016-06-24)
we have a PDF preview with a javascript PDF view, which is much better way
of viewing PDF.

This commit made the Thumbnail preview obsolete, also it does not really
work on ERP5JS, so remove the thumbnail preview.

See commit ec3c9cbc.

payment transaction group workflow's deliver action is a two step delivery,
which "start delivery" and wait for an interaction to finish the delivery.

Add a default interaction workflow which finishes the delivery immediately,
otherwise the payment transaction group stay in delivering state when user
use the Deliver workflow action.

For same reasons as f692aa61 ([erp5_bank_reconciliation] Rename
your_mode field, to prevent naming conflict in hal, 2019-10-23)

Enable the "select column" of the listbox so that user can choose one by
one the lines to add to the group. The default action, when nothing is
selected, remain the same "select everything".

This uses a listbox search column, which is not yet supported in ERP5JS,
so for now the feature is only available in erp5_xhtml_style.

Show an empty listbox at the beginning, that will be populated when user
start to search.
This is required if we want the ?reset=1 from the action URL to really
reset the selection.

This list is currently not sortable, so don't show sort column

This was often leaving a comment with 'None'

Checking that for all lines:
 - bank account is set, for both sides
 - bank accounts have IBAN and BIC
 - bank accounts are validated
 - bank accounts belong to the section (to prevent problem when cloning
and not changing the bank account)

These constraints are present in a property sheet that have to be associated to
accounting transaction movement portal type in a configurator step, and also as
assertions in the file generation.

and only show the generate credit transfer action if the payment mode is correct.

For historical reasons, PDF to text involved conversion first of the PDF to
png, then this png to tiff and the tiff was sent to tesseract. This works, but
it consumes a lot of resources with large PDFs, especially because the
intermediate png/tiff are created with a resolution of 300 DPI, which easily
needs serveral Go of RAM and temporary disk space.
This was obsorved with the PDF created by erp5_document_scanner, which are
usually high quality (1 or 2Mo per page) and even a one page PDF sometimes
took more than one minute to OCR.

Since 9.53 ghostscript integrates tesseract engine directly, we don't need to
prepare a tiff beforehand, we can directly send the PDF data to ghostscript.

These change use ghostscript if available and otherwise fallback to the same
pipeline as before. This will allow the transition until all ERP5 instances
are running a recent enough SlapOS with ghostscript 9.54. Fortunately, before
SlapOS include ghostscript 9.54, ERP5 software release did not have ghostscript
in $PATH, so we don't have to check ghostscript version, we assume that if gs
is in $PATH, it means we have a recent enough SlapOS.

This new approach was less tolerant regarding broken/password-protected PDFs
so we perform a new check that the PDF is valid and not encrypted before
trying to use OCR.

Wendelin.core is now integral part of ERP5 (see [1,2]), but nothing
inside ERP5 currently uses it. And even though wendelin.core has its own
testsuite, integration problems are always possible.

-> Add test to erp5_core_test that minimally makes sure that basic
wendelin.core operations work.

This test currently passes with wendelin.core 1, which is the default.
It also passes as live test with wendelin.core 2.
However with wendelin.core 2 it currently fails on testnodes like e.g.

    ValueError: ZODB.MappingStorage.MappingStorage is in-RAM storage
	in-RAM storages are not supported:
	a zurl pointing to in-RAM storage in one process would lead to
	another in-RAM storage in WCFS process.

and

    RuntimeError: wcfs: join file:///srv/slapgrid/slappart8/srv/testnode/djk/test_suite/unit_test.2/var/Data.fs: server not started
    (https://nexedijs.erp5.net/#/test_result_module/20210530-92EF3124/102)

because we need to amend ERP5 test driver

1) to run tests on a real storage instead of in-RAM Mapping Storage(*), and
2) to spawn WCFS server for each such storage.

I will try to address those points in a later patch.

In the meantime there should be no reason not to merge this, because we
do not use wendelin.core 2 yet, and solving "1" and "2" first are
preconditions to begin such a usage.

/cc @rafael, @tomo, @seb, @jerome, @romain, @vpelletier, @Tyagov, @klaus, @jp

(*) Combining Zope and WCFS working together requires data to be on a real
    storage, not on in-RAM MappingStorage inside Zope's Python process.

For SEPA files "End to End ID" we need a reference on payment transactions.
In the first prototype, the reference was set at the time of generating the
file, but it's a non common behaviour to generate reference when producing
reports, so we changed to ensuring payment has reference when adding to the
group.

Instead of using only setAggregate(), specify a portal type
to consider only payment transaction groups.

Because of the wrong TALES, jump and select was not working on the aggregate
relation field on accounting transaction line.

Support generating pain.001.001.02 credit transfer from payment transaction
groups.

Having a portal type is required to use the listbox as "Proxy Listbox ID" in a
relation field.

Follow the same rule that allow other organisations from the same group to
use bank account from the main section when selecting the payments and
displaying the payments from the group.

This constraint will have to be enabled by configurator/upgrader.

Instead of selecting already stopped payments, introduce a new "mode" field in
the dialog, where user can choose the previous behavior of selecting stopped
payments, or a new behavior where user would select planned or confirmed payments,
in that case the payments will be automatically stopped before being added to
the group.
