  mac802154: Avoid new associations while disassociating (2023-12-15 11:14:57 +0100)

----------------------------------------------------------------
This pull request mainly brings support for dynamic associations in the
WPAN world. Thanks to the recent improvements it was possible to
discover nearby devices, it is now also possible to associate with them
to form a sub-network using a specific PAN ID. The support includes
several functions, such as:
* Requesting an association to a coordinator, waiting for the response
* Sending a disassociation notification to a coordinator
* Receiving an association request when we are coordinator, answering
  the request (for now all devices are accepted up to a limit, to be
  refined)
* Sending a disassociation notification to a child
* Users may request the list of associated devices (the parent and the
  children).

Here are a few example of userspace calls that can be made:
iwpan dev <dev> associate pan_id 2 coord $COORD
iwpan dev <dev> list_associations
iwpan dev <dev> disassociate ext_addr $COORD

There are as well two patches from Uwe turning remove callbacks into
void functions.
