This reverts 8a5f5b5b (ZMySQLDA: fix string_literal usage, 2023-03-14)
to apply this logic one step lower, because CMFActivity uses
db.string_literal directly.

this works with astroid 3.2.0 and pylint 3.2.0

on python2, we use have a [python patch][patch] to globally make
asyncore use poll, at that time we were using medusa and it was not
exposing an option to use something else than select.

[patch]: https://lab.nexedi.com/nexedi/slapos/-/blob/180f1553fa7774f05ae8e739dfef43fa2ae56c0a/component/python-2.7/asyncore_poll_insteadof_select.patch

also add the missing tests

Because the librairies used here were never ported to python3.

Notable changes:

  - ERP5Site_createGoogleUserToOAuth is dropped
  - internal API changed radically, so customizations made by overriding
    scripts are broken.
  - the core logic is now implemented in a connector class (still in
    portal_oauth for simplicity, but it would be simpler to move it to
    portal_web_services)

No changes required in the google console, the redirect uri is still
ERP5Site_receiveGoogleCallback

page templates unicode resolver already takes care of coercing when
needed and this is directly compatible with python2 and python3

This only works on python2

The test testCMFActivity.TestCMFActivity.test_onErrorCallback was
failing because some weak references were not dropped.
The reason was that _DequeueMessageException was declared as global
and it kept a traceback including the variables pointed by the weak
references, preventing their garbage collection.
This was fixed by using a class for the _DequeueMessageException
instead of a singleton, and creating a new instance on every raise.

This test assumed that activating a method with a string of length `n+x`
as argument would be serialized in `x` more bytes that activating the
same method with a string of length `n` as argument, which is only true
for protocol 0 for multiple reasons ( short strings and long strings
are serialized differently, "frames" are used with protocol 5) and
db.string_literal seems to introduce a difference.

Change the test to mock Message.dump to produce longer dumps instead of
relying on this assumption.

_resultForDoCleanups no longer exists on python3, getting the status
of a test in teardown is very different accross python versions ( see
https://stackoverflow.com/q/4414234 ) and just executing this code when
the test failed only has the problem that a test method may count as
two failures or errors, which is after all not a big problem.

to make sure test terminates in case of problems with webdav server

When a test needs to login as manager again, the best way is to use
${manager_username} and ${manager_password} set in cookies before
running tests.

This is continuation of 445e8fa8 (ERP5TypeTestCase: rework default
manager password generation, 2024-05-27)

form_dialog was different from form_render (that is used in form_view
and form_list) regarding the <legend> element for form groups:

 - the element was unconditionally present, unlike form_render where it
 is only displayed if non empty
 - the text was not translated
