Auto-generate cache_id, removing the risk of duplicating one.
Inline getInstanceID as it is its only caller left.
Avoid wrapping if getTransactionalVariable cannot be imported.
Avoid intermediate variables, at the cost of dupicating logic but
accelerating run-time.
Use functools.wraps .
Access _cache_sequence_number directly - these pieces of code are friends
anyway, we already set a volatile property on Catalog instance. Saves one
getattr and one call.

No backslash at EOL.
Avoid splitting messages, to ease code lookup.
LOG's "error" argument accepts a boolean, which removes the need to touch
sys.exc_info.
Use modern exception raising syntax.

_getSelectDict was also calling itself on sub-sql_expressions, but this
was useless: they would already have called it, and discarded one of its
returned values. Instead, preserve both returned values in __init__ and
access these attributes directly when iterating over sub-sql_expressions.
Also, fold canMergeSelectDict back into its only 2 call places, saving one
getattr and one call.
Also, get rid of a few properties which were only used in _getSelectDict.
Also, get rid of two iterable copies: sql_expression_list when it is
already a list (no need to cast it again to a list, we just built one with
the list comprehension), and select_dict being cast into a list when
entering _getSelectDict, despite not being used (besides in extra
_getSelectDict calls, which are now entirely avoided).

Because some tests or softwares can chmod'ed some files to make them
readonly, testnode should try to chmod the files to deletable state if
deleting them fail in the first place.

Telephone.asUrl (which is used in erp5_short_message) properly supported
detailed coordinates, but had no support for coordinate text.

In that case, we don't try to be to clever and just use the coordinate
(almost) as is, just using the tel: prefix and removing spaces which are
not legal.

A pprofile run shows DateTime_or_None costing 3ms per value (including all
callees).
While this may seem low, it is common to receive hundreds of such values
in single query results (ex: web mode document & webpage lookups),
so the total time spent parting dates per query can become significantly
larger than the time to execute the query itself.
In the case of this measure setup, 504 dates were processed for a total of
1.5 seconds.
DateTime is slow to parse strings because it cannot rely on a pre-known
format. With MySQL/MariaDB, the format is know for those column types, so
implement specific parsing to get better performance.
On the same setup, pprofile run shows a parsing time of 123µs per value in
DATETIME_to_DateTime_or_None, or 65ms total.
DATE_to_DateTime_or_None should not deviate significantly from this.

For some reason, unit tests all broke while testing this revision. The
relation between both is not clear to me (this code has worked for me).
In doubt, I revert it for now.
This reverts commit 0057272c.

getRelativeUrl and restrictedTraverse are expensive operations. Do not
involve them pointlessly.
Also, boolean evaluation of lists is a thing.

Categories are member of themselves. When a category is renamed, the membership to self was already preserved thanks to nexedi/erp5@7f2e8eb2
, but this was not the case when a category was cut and pasted.

There are two different cases:
 * When just created, a category is member of itself because this is the [default behavior](https://lab.nexedi.com/nexedi/erp5/blob/b705495de0f04645b7b3ad3b74c46de00c923876/product/CMFCategory/CategoryTool.py#L1193-1196) for categories not having categories set. In this case, it's dynamic.
 * When category has some categories set ( in `self.categories` ) - this happens for example after being renamed - then behavior is different and `self.categories` has to be updated.

7f2e8eb2 was handling properly the later case after a clone, but not in a cut and paste ( move ) scenario, because in this case "after clone" hook is not called.

The first idea was to move the same hook at another level by overloading `_postCopy` but after some discussion and thinking, it seemed more logical to make sure `CategoryTool.setCategoryList` does not save categories membership to self, which is consistent in the way `CategoryTool.getCategoryList` adds the membership to self dynamically.

This MR brings a few more tests, so that we can claim [#1900](https://nexedi.erp5.net/bug_module/1900) and [#704](https://nexedi.erp5.net/bug_module/704) are tested enough and close these old bugs.

With commit babbf56f, some objects that were
not indexed are now indexed, and this fails when these objects can't be indexed.

An exemple is when a PythonScript is stored inside a Web Site:

  Traceback (innermost last):
  Module Products.CMFActivity.ActivityTool, line 1360, in invokeGroup
    traverse(method_id)(expanded_object_list)
  Module Products.ERP5Catalog.CatalogTool, line 939, in catalogObjectList
    super(CatalogTool, self).catalogObjectList(tmp_object_list, **m.kw)
  Module Products.ZSQLCatalog.ZSQLCatalog, line 828, in catalogObjectList
    catalog_value=catalog,
  Module Products.ERP5Catalog.CatalogTool, line 875, in wrapObjectList
    - __traceback_info__: (<PythonScript at /erp5/web_site_module/...>,)
    and document_object._getAcquireLocalRoles():
  AttributeError: _getAcquireLocalRoles

Before, such object was skipped because it does not have recursiveReindexObject.
