As requested [here][1], help with removing calls to
`wmem_packet_scope()` in favour of references to `pinfo->pool`.

* Plugins chosen semi-alphabetically.
* When a calling function already has a `pinfo` argument, use that.
* If a function seems narrowly focused on getting and (possibly)
  returning memory, change the function signature to take a
  `wmem_allocator_t *`.
* If it seems more focused on packet-based operations, pass in a
  `packet_info *` instead and use `pinfo->pool` within.
* This is meant to be a light first pass for quick wins.
  Some of the files affected by this MR still have references to
  `wmem_packet_scope()` where it would take significant work to remove.
  These will need revisiting later.
