We don't need Permissions.ModifyPortalContent, Permissions.AccessContentsInformation
is enough. This is consistent with the security declarations in Base and
Folder.

I did not identify this monkey-patch.

- Ignore node preference when spawning activities.
  Otherwise, activities which are not spawned with a preferred node will
  get an effective priority penalty compared to same-priority activities
  spawned *with* a node preference, despite both being to execute by the
  same processing node.
- Break activity processing loop when the current processing node is also
  the activity validation node.
  This avoids pathological cases of activity accumulation, for example when
  reindexing an entire site: _recurseCallMethod is spawned in
  processing_node=0, but immediateReindexObject is spawned in
  processing_node=-1 because of serialization_tag dependency, so with such
  loop _recurseCallMethod will be executed over and over, piling indexation
  activities up until _recurseCallMethod does not self-respawn.
  In turn, such activity accumulation lead to an increased overhead, and
  decreased activity processing efficiency.
  This may also allow multi-node instances to more reliably use the
  validation node as a processing node.

The cost for multi-node instances of these changes should be absolutely
minimal (no extra IO necessary, minimal extra code).
A possible drawback on single-node instances is that tic period may become
more important because process_timer will return more often.

If one callable has the default ID '1', it will break nearly all newContent calls on empty object

Adding **kw prevents "Unexpected keyword argument 'select_favorite'".
The removed arguments url, user and password aren't used by the Script and can therefore be removed.

Allows using an empty fallback value with "replace" set to trigger header
removal.

This stopped working when the signature of Message.__init__ changed in

"Access Tool" sounds like a tool to access, but this setting is about
giving access to ERP5 tools from the module list.

we have such error:
