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>, ...]

Ran https://github.com/python/cpython/blob/3.7/Lib/lib2to3/fixes/fix_asserts.py after adding the missing methods (assertRegex and assertRaisesRegex) on ERP5TypeTestCase.

Also ran a custom fixer rewriting
 
```py
self.assertTrue(a in b)
```

into

```py
self.assertIn(a, b)
```

Unindexation happens in a transation after the corresponding document was
deleted. So there is no context available to check the type of the deleted
document. So these filter expressions are meaningless.

    needle = results['needle']

    method_map = {True: 'assertIn', False: 'assertNotIn'}
    method_in = meth.value == 'assertTrue'
    if 'not' in str(needle.parent.children[1]):
      method_in = not method_in
    meth.replace(Name(method_map[method_in], prefix=meth.prefix))

    needle.parent.children = [needle, Comma(), haystack]

so that we can run 2to3.fix_assert

This updates the change to 32cead86 (xhtml_style: set a bottom
margin for dialog action, 2019-05-31) that got impacted by a rule
added on html and body in 5dde17a5 (xhtml_style: make editors in
bottom group use full height, 2022-08-22)

this code was latin 1, causing issues for refactoring scripts

Form.__call__ replaces page template call, so it is also responsible
to set the content type in response.

With Page Templates, ZopePageTemplate._exec (called by
Shared.DC.Scripts.Bindings.__call__ and _bindAndExec) sets the
response content type and calls pt_render. Form.__call__ also calls
pt_render, so to behave like page template, it should also sets the
response content type.

In erp5_xhtml_style, we don't notice this, because global_definitions
contains a setHeader call to set content type to html.

Check that it correctly includes the web page and sets the content
type header.

it would be good to rewrite this in a page template

This method converts the HTML, so it should escape nasty HTML tags.

Also add missing escaping when inserting the base

and move it to erp5_administration, this is not a "core" feature but
just a developer tool.

It was used in a few tests, move all the tests in testERP5Administration
