for same reason as the xhtml_style version, there is no problem with
having more than one listbox, see d2dedca3 (core: remove useless log

Use same label as the action, "Preview"

These scripts take time to run, so restrict them to Manager users.

  The render is useful to preview content after edit while doing a gadget or on other contexts.

  Since corportate identity has erp5_web as dependency, it cause no harm to move.

   * const is handled as enum with a single value automatically
   * patch ensureArraySize to not modify the user input, let the user safely slice by himself.
   * Reorganise patches so it is grouped by prototype

Improvements compared to the previous implementation:
- avoid looking up the user document again, when the PAS plugin already did
  that job
- make it possible to call a single script when multiple sources of groups
  are based on the same documents, avoiding iterating unnecessarily on
  those same documents multiple times
- avoid repeating the same membership value (ex: when a user has multiple
  assignments with a common membership subset)
- avoid resolving the same relation more than once
- do not go from document value to relative URL only to go from relative
  URL back to document value at the next step
- move security group id extraction to unrestricted python, as the security
  overhead was taking a large amount of time
In a security setup with 8 scripts (all Assignment-based), 6 base
categories, and 4 Assignments (all valid), this implementation is 10 times
faster at producing the same group id set as the previous one.

   This prevents loose data and wrong edits.

   XXX update description on a squash to explain better.

The `write` method of the `output` object was being overwritten
in live tests, replacing it to a function that printed both to
the output and to stdout. This was not necessary, as it is
possible to use this function directly. Moreover, the function
code had two flaws:
  - It assumed that output was a particular (StringIO) class.
  This caused a problem during the migration (commit
  80bd30fc820d273d18d9c54566137301d9c40a4c).
  - It printed to stdout instead to stderr.
Using the function directly allows `output.write` to be used
inside it, preventing the first flaw. The second flaw has also
been solved.

This is no longer needed now, maybe since Zope4 or maybe since a patch
in slapos. This option does not exist on python3 and using pylint on
python3 complains about these disable, so we have to remove them on
python2 as well.

See merge request nexedi/erp5!1912

This makes consistent method resolution order with python3 and reveal a
problem that relation field widgets render_pdf was not the expected one
on python3, solve this by defining explicitly the method.

roundDebitCredit does not raise in case of big difference since

This assertRaises syntax does nothing on python2 and was an error on
python2. Update the test to test the actual behavior

When trying to use `MemcachedTool` without the `python-memcached` package,
a dummy implementation is supposed to allow installation while giving a
warning when called.

This dummy implementation was broken because it was calling a wrong class,
named `_MemcachedTool`, which did not exist. Instead, `_MemcacheTool` did
exist and was used for the real implementation.

This commit renames `_MemcacheTool` to `_MemcachedTool` to allow dummy
implementation to work.
