[PATCH batadv v2 0/6] batman-adv: tt: atomic_t sashiko fixes

There were a couple of sashiko reports regarding the
batadv-next-pullrequest-20260728 PR. I went through the TT code and tried
to handle them and at the same time already predict what else sashiko might
report as next. I needed to change the batadv_tt_local_remove() hash
interaction as preparation for the related NEW flag (and counter) handling.

And the netdev maintainers rejected this approach (for now). I had to
re-add the atomic_t code parts back in this patchset.

Changes in v2:
- rebase on main
- add "batman-adv: tt: use atomic flag modifications" and "batman-adv: tt:
  simplify NEW flag transition code" because they are reverted on main
- add patch to extract the roam "add" code in a separate function
- make the "simplify NEW flag transition code" patch independent of atomic_t code
- Link to v1: https://patch.msgid.link/[email protected]
