modules_k/presence: Dedicated notifier processes

- This fixes a bug in presence where, when subs_db_mode is database
  only, under high loads with lots of presentity changes you can get
  several different NOTIFY requests sent with the same CSeq.
- The dedicated notifier processes only work when in database only
  mode.
- The dedicated notifier processes are enabled (with one notifier
  process) by default when in database only mode.
- You can disable the dedicated notifier processes by setting the
  "notifier_processes" modparam to 0.
- The notifier processes are executed on a timer and deal with a
  small amount of the outstanding notifications each time they run.
  By default (changeable through the "waitn_time" modparam) all
  dialogs are processed every five seconds.  This means it will take
  between 0 and five seconds (on average 2.5 seconds) between a
  presentity or dialog update occurring and a NOTIFY request being
  sent.
