Fetch usage can be bypassed to do not use service worker when not needed.

As appcache has been dropped on Firefox, this change will improve the speed on Firefox.

No change is expected on Chrome/Safari.

[erp5_web_renderjs_ui] Replace Base_getListFileFromAppcache with Base_getTranslationSourceFileList.

Collect a list of files from service worker code.

[erp5_web_renderjs_ui] Fix rjs_gadget_erp5_serviceworker.js. Use cache.add because safari does not support cache.addAll.

[erp5_web_renderjs_ui] Fix rjs_gadget_erp5_serviceworker.js to fix Firefox Cache Storage problem.

Don't give request object itself to cache.match. Firefox's Cache Storage does not work properly when VARY contains Accept-Language. Give URL string instead, then cache.match works on both Firefox and Chrome.

[erp5_web_renderjs_ui] Stop calling skipWaiting() and clients.claim() for the new service worker.

To preserve the consistency of code and data, let the new service worker wait until all tabs and windows of the old version are closed.

[erp5_web_renderjs_ui] New client can use the latest cache without waiting for the new service worker to be activated.

And once client was associated with a cache, client keeps using the same cache.

[erp5_web_renderjs_ui] Fix translation script. Get service worker filename from layout property. Don't hardcode it.

[erp5_web_renderjs_ui] Fix service worker. Don't hardcode the special cache name.

The name must be different per web site, else if the same service worker code is used by multiple web sites in ERP5 web site module, service worker does not work correctly.

[erp5_web_renderjs_ui] Add more comments because service worker is unstable and hard to use safely.

[erp5_web_renderjs_ui] If service worker failed to install cache, unregister this service worker explicitly.

[erp5_web_renderjs_ui] Clean up service worker code. Remove many `if`.

[erp5_web_renderjs_ui] Update service worker code. Use lower case for non-global variables.

[erp5_web_renderjs_ui] Update service worker code. Client_id is null when it is the first request, in other words if request is navigate mode. Since major web browsers already implement client_id, if client_is is null, let's use the latest cache and don't get cache_key from CACHE_MAP and erp5js_cache.

Allow edition in the new UI

This make everything slow as hell and prevent to quickly save.

Fix remaining functional test failures and drop a few more code that become unused now that we have a `setFile` command.

Because firefox 68 executes event handlers for events triggered on disabled elements ( https://phabricator.services.mozilla.com/D10000 ), Zelenium is also adapted to mimic the behaviour we had with firefox 52 (and chrome behavior) of not executing event hander.

TODO:
 * [x] `testContributeTab` sometimes displays Converted, sometimes Converting. I wonder if we can wait for something to make the test deterministic, otherwise we can assert a regexp.
 * [x] `erp5_web_renderjs_ui_test:testFunctionalRJSCore` ( discussed in nexedi/erp5@05b9c4af (comment 87278) )
 * [x] someone update test nodes to use new firefox.
 * [x] understand why with firefox 58 selenium sends clicks on disabled button.

Volatile attributes may disappear from one statement to the next.
Make code reliable by moving it one level up the call stack, removing the
need for volatile attributes.
_setId and _postCopy get back to their original "copy of OFS.CopySupport"
status (see comment at beginning of file).

This BT contains the same category twice.

Bank Account, Currency{, Module}, Currency Exchange {Cell,Line} already
exist in erp5_base, which is a dependency of this Business Template at
least through erp5_trade.
"composition" and "variation" Base Categories exist in erp5_pdm, which
is a dependency of this Business Template via erp5_trade.
"site" Base Category exists in erp5_base, which is a dependency of this
Business Template via erp5_trade.

classification is already provided by erp5_dms, which is a dependency
of this BT already.

requirement is also present in erp5_project. So add a dependency on that BT
and remove the duplication.

This BT achieved the rare feat of containing the same document twice.

region/europe/western_europe is also present in erp5_tiosafe_test, which is
already installed in the same unit test. So add a dependency on that BT and
remove the duplication.

currency_module/euro is also present in erp5_tiosafe_test, which is already
installed in the same unit test. So add a dependency on that BT and remove
the duplication.

Vincent Pelletier:
- Disable timeout by default.

Vincent Pelletier:
- Ignore TimerService-originated publication requests.
- Add copyright headers.
- Disable timeout by default.
- Give a meaning to requested negative deadlines.
- Docstrings.
- Assorted simplifications.

The Assigments are only relevant if the User is based on Person Document, on SlapOS, an user come from a Computer or a Software Instance Document. This change makes the document compatible with other kinds of Users, as Assigment is overkill for Non-Person cases, as the presence of ERP5 Login is enough to determinate the User existence. 

The other alternative would be re-factorize to not duplicate code, which seems not the intention of how this code was written.

Simpler, and reduces the exposure of exc_info (which can be tricky to use
in other contexts).

When we updated Firefox from 52 to 68, the behavior of firefox changed.
With 52, when calling element.dispatchEvent on a disabled element, the
event handlers were not executed, but in 68 they are.
