We are already closing Storage on shutdown (see nearby Storage.close call in
the patch), but the DB handle was not closed. With classic ZODB it does not
really matter in practice, because not closing DB is only leaking RAM resources
and the program is anyway terminated soon.

However with wendelin.core 2 things are different: in addition to ZODB storage
server, there is also synthetic WCFS filesystem from which files are opened
and memory-mmaped. In runUnitTest we start both ZODB and WCFS servers and we
also shut down them both in the end. The filesystem server can be cleanly
unmounted and shutdown only when there are no opened files left on it.

Wendelin.core 2 client works by complementing each ZODB connection (zconn) with
WCFS-level connection (wconn) to WCFS server. Those two zconn and wconn are
kept in sync by wendelin.core 2 client logic: whenever zconn adjusts its view
of the database, so does wconn. And whenever zconn is garbage collected, so
does wconn is closed to release resources and close corresponding files opened
on WCFS. In addition to garbage-collection, wconn is also closed when zconn.db
- the ZODB DB handle via which zconn was created - is closed. This is needed to
be able to reliably trigger freeing WCFS resources, because even after DB is
closed, zconn can still stay alive forever being referenced from some python
object - e.g. a frame or traceback or something else.

The latter scenario actually happens during runUnitTest run. As the result it
leads to inability to unmount and stop WCFS server cleanly:

    $ ./runUnitTest --load --save --with_wendelin_core -v erp5_core_test:testWendelinCore
    ...
    test (erp5.component.test.erp5_version.testWendelinCore.TestWendelinCoreBasic) ... ok

I've debugged things a bit and even with
kirr/ZODB@bbd03b3a ZODB connection stays alive
being referenced from some frame objects.

-> Fix this problem by explicitly closing ZODB DB nearby tests shutdown before call to wcfs_server.stop

This is follow-up to 5796a17a (core_test: Add test to make sure that
wendelin.core basically works; nexedi/erp5!1429).

In that commit it was said that testWendelinCore

    "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 when run on testnodes
     ...
     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."

This patch addresses that latter problem to run testWendelinCore under
testnode infrastructure.

@rafael and @jerome suggested that we can force a test to be run on a
real storage via `runUnitTest --load --save` or via `--activity_node=n`.

@rafael also suggested not to generally change the testing driver, but instead
make step-by-step progress and first tag each test that uses wendelin.core with an
option. Let's go this way now: runUnitTest/custom_zodb are taught to launch
WCFS server if wendelin.core usage is requested and software is built with
wendelin.core 2.

With both changes combined testWendelinCore should now pass OK when run
on a testnode with both wendelin.core 1 and wendelin.core 2.

This patch is based on a draft patch by @rafael: https://lab.nexedi.com/rafael/erp5/commit/14e3a777.

This patch also relies on recent wendelin.core 2 wcfs.py rework which
exposed functionality to start WCFS server and to further control it:
kirr/wendelin.core@5bfa8cf8.

With software release test suites, there are probably
files/folders with permission issues.

By setting XORG_LOCK_DIR, we can isolate processes when running on slapos test
nodes, so that instead of having all test runners used the shared /tmp, which
eventually fail with

    EnvironmentError: All displays locked : [':123', ':124', ':125', ...

errors when too many testnodes are currently running or too many testnodes have
left some stale lock files. Eventhough since fbdb4ec9 (test: Do not check
presence of lockfile in /tmp/ to assume Xvfb is running for this display, 2017-06-07)
things have improved, it happens that the lock files are owned by a different
unix user (because it was left by another testnode), then Xvfb is not able to
remove the stale lock file.

This is backward compatibility code for previous commit.

With bf57228a ([erp5_core] RelationField listbox must also fetch
default_params value from the relationfield, 2018-05-09), we introduced a
regression that listboxs from relation fields "proxy listbox ids" default params
where no longer used. As a result, if we have a listbox which define some
catalog search with default parameters, like for example the "Suppliers" or
"Clients" listboxs from erp5_trade are doing, these parameters were not
taken into account. In the case of trade listbox, this was showing all nodes.

This changes Base_getRelatedObjectParameter to get catalog search from the
proxy listbox if there is one.

trade_renderjs_ui_test: tests for "Suppliers", "Clients", "Organisations" and "Persons" Proxy Listbox Ids

This is mostly for editor fields, to fix the problem that components were
edited by the text editor and not the code editor.

Editor is selected by Base_getEditorFieldPreferredTextEditor, which will
use a text editor by default, unless the document has a content type, in
which case it will return the most appropriate editor, which is by default
the source code editor for documents whose text content is not text/html.

It's anyway not wrong to have a content type defined here, Components
are TextDocuments and TextDocuments usually have getContentType method.

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

renderjs_ui_trade_zuite is the tests from trade_zuite ported to ERP5JS.

Some old tests were not ported yet

Init script just have to print "Data Created."

init macro no longer redirect to the order created by
Zuite_createSaleOrderForTradeZuite, so that it's more reusable.

The URL was in the description, so this action was not working since a409a7e6
(Fix jump action by using Base_jumpToRelatedObject to jump and
Base_checkPermission to check that the destination module is visible, 2008-12-02)

renderjs_ui_pdm_zuite is the tests from pdm_zuite ported to ERP5JS.

Using the same message as in Base_jumpToRelatedObject

getRelatedValueList seems to have changed in behavior at some point, when
passed multiple base_category_list, it only returns document that are member
of all the categories. Since this API is inneficient here (it searchs catalog
unrestrictedly and then apply check one by one the documents in python), we
change to use portal_catalog which is much better suited for this kind of
queries.

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.
