This works only for medusa, using the same approach as CMFCore's
CookieCrumbler

This function have evolved to something very trivial not accessing anything from database, so caching this no longer really makes sense, also the cache keys are really big.

On a quick benchmark of calling ERP5Site_getTabList 10000 times:
with cache: ERP5Site_getTabList took 12.961781
without cache: ERP5Site_getTabList took 5.395873

Only send line data if the text is not empty and ensure there is no hole
in the uid list.
This will fix the edition when the field already contains some homonyms.

Only append empty input if the latest one is not empty.

Replace verify by assert in the tests.

When we ignore variations, we should also ignore them when looking
to update existing orders

erp5_web_manifest_test:testManifest leave a -1 activity.

W3Validator seems obsolete now since it does not validate HTML5. nu became the default validator in 417ff1ae.

Add some tests and fix bugs:
* https://nexedi.erp5.net/bug_module/20170426-A3962E
* another bug that columns names were not escaped ( in a project we have a custom table with a column named `use` and this breaks `upgradeSchema`  )

Since 8a6c4394 Item_getTrackingList sets
parent and id on brain instead of url.

testItem now passes: https://nexedijs.erp5.net/#/test_result_module/20190625-614B59A1

This first work on WSGI is only to stop using ZServer (Medusa),
which is a required step before moving to Zope 4. This means that
Zope should behave almost exactly the same way as before, notably:

- We don't take advantage yet of what WSGI offers, like IPv6.
- There's extra code to handle errors the same way as before
  (this is something we'll have to change for Zope 4).

The most significant change in behaviour is that the chosen WSGI server
(waitress) does some of the HTTP work in worker threads (Medusa does it
entirely in the IO thread), and the biggest consequence concerns the
deadlock debugger that is now run from the worker thread:
- it does not work if all threads are blocked
- doing better would require to patch waitress in a quite ugly way

About TimerService, we simplify things by removing the egg.
In zope.conf, it's possible to import from the product.

/reviewed-on nexedi/erp5!883

At the same time, timerserver is no longer distributed as an egg.

zope.globalrequest is a new dependency of Zope 4
and it is already used by the backported WSGIPublisher.

Parts of ZPublisher.utils are also backported.

This is a preliminary commit that only adds a verbatim copy of WSGIPublisher.py

Clinking on the rows of item tracking view was not working in renderjs ui.

Fix request value modifications

Do not mark fields as required
The RJS field marks it as required, and user can't submit anymore.
Instead, use an external validator to only require the field when the user submit

clicked on the update button

Do not crash if the form can not be fetched.

Formbox context can be a listbox cell.

These are very outdated stuff (pre-Business Templates), they do not scale
and (except ImportExportSkins) try to write to a paths which should not
exist.

Especially in chrome (75), it's very hard to see selected text in erp5
xhtml style interface, especially in listboxs.
Chrome adds a background color to selected text, but this background is
almost same color as ERP5 background.

This uses https://developer.mozilla.org/en-US/docs/Web/CSS/::selection
to make it visually clear what is selected.
