Update ZMI pages with the design of Products.ZMySQLDA and with the
usage of manage_page_header, which sets the content-type to html

fixup! ERP5Catalog: Fix UnicodeDecodeError on non ascii catalog search when the inituser name is unicode

variable was not zope_testSearchNonAsciiWithLegacyUserFolderUser

Products.CMFCore.CachingPolicyManager.CPMCache became a new style class

because __str__() returns id in Zope2 but returns login in Zope4.

XMLExportImport encode strings in base64 when they can not safely be
represented in XML (including for exemple "\n"), so we can not use
this information to decide if this a BINBYTES or a BINSTRING pickle
opcode.

For now, it's still unclear how bytes and str should be handled, so
while using python2 it's better to keep using str everywhere and not
introduce zodbpickle.binary that looks like str on python2 but will
become bytes on python3 and have consistent data everywhere (ie.
everything str)

BINBYTES is not fully removed from the patch, because we'll want to
use it later, but it is in "if" that is always false.

This reverts commit c45c2295.

to get test passing again

On Zope4 these settings are no longer in zope.conf

We now target transaction 3 so this patch is not longer compatible and
no longer needed according to discussions on the launchpad issue.

_sort_key is also set to '1' on recent Products.ZSQLMethods

For now, remove it completely. If necessary `registerHelp()` can be used.

    Removed the old help system, in favor of the current Sphinx documentation
    hosted at http://docs.zope.org/zope2/. For backwards compatibility the
    `registerHelp` and `registerHelpTitle` methods are still available on the
    ProductContext used during the `initialize` function.

Unlike StringIO.StringIO().tell() and open().tell(), which all return
int, io.BytesIO().tell() returns long. Because io.BytesIO is used when
uploading files on Zope4, this cause PropertySheetValidity errors when
checking consistency, because Data.size property is expected to be int.

Checks that created document types match constraints

Previously, we were using an encoded string, which in practice worked,
but with python3, WSGI server will encode as latin1 (because WSGI is
latin1) and already with Zope4 on python2 we have issues with testing,
as functional testing fake WSGI server only accepts ascii headers [1]

Since Zope 4, the `standard_error_message` is rendered in the context
of REQUEST['PUBLISHED'], which in case of publishing a skin (page
template or script) in the context of a document is is the skin itself,
but for error rendering in case of erp5_web Web Site or Web Section,
we expect standard_error_message_template to always be rendered in the
context of the document, that's why we use REQUEST.PARENTS[0] as context.

REQUEST.PUBLISHED = <PythonScript at /erp5/script used for /erp5/module/document>
REQUEST.PARENTS [<Document>, <Module>, <ERP5Site>, ...]

No longer needed on Zope4, from commit dc5b9292f (Merge pull request
 387 from zopefoundation/re-379-revert-repr, 2018-10-26)

Call the original method instead of copy/pasting the code

We still keep the following patches:
 - user: this is an ERP5 addition and maybe we use it in customer project
   code (if we don't I'm in favor of removing the feature, it's used in
   only one place in this repo)
 - call `self.changeSkin(self.portal.getCurrentSkinName())`. Maybe this
   is needed for CMFCore tests and could be good to send upstream, I did
   not check this part

`zope_quick_start` was a dtml that was removed in Zope commit c8e4cd5ca
(Simplify control panel objects and actually make them non-persistent.,
2016-08-14), but it is referenced in /index_html page template, which
contains:

    <tal:text tal:replace="structure context/zope_quick_start" />

As a result, rendering / is an error page because of KeyError: 'zope_quick_start'

In SlapOS setup, we are using / in an haproxy health check, so the
health check fail and zope is marked as down and haproxy does not send
requests to backend.

We could have an upgrader constraint to repair this page template, but
because of this, zope is unreachable through haproxy, so it's easier to
ressort to monkey patching.

Zope4 inituser is decoded by decode('utf-8') on Zope startup and it is unicode on python2,
therefore it raises UnicodeDecodeError when searching non ascii charater on catalog.

This is necessary on Zope4 because the error page is executed even if
the response already has a locked body - and in this case we don't
want to override the content-type header that might also have been set.

One user of this is Base_redirect from erp5_hal_json_style, when
abort_transaction is True, in that case it sets a body in json, a
content type header of application/json and then raise a redirect so
that the transaction is not commited. This fixes a problem visible on
Zope4 with erp5_bank_reconciliation_renderjs_ui_test:testFunctionalRJSBankReconciliationAction

Even if this is not used because we have locked a status earlier, the
constructor expects an URL with zExceptions 4

zopefoundation/Products.CMFCore commit 882a697 (- correct check for
request compatibility for CookieCrumbler, 2017-05-12)

This drops some patches that should no longer be needed with zope 4 to
only keep the publisher timeout changes

Zope4 uses urlparse + urlunparse to encode the URL, which has a side
effect of removing the empty fragment from the URL. Using a lower level
API to set the status code and the Location header we achieve the same
result.
