Locking pf normalization code:
- Make struct pf_frent, pf_frcache, pf_fragment
  private to pf_norm.c.
- Make fragment UMA zones, TAILQs and RB-trees
  static to pf_norm.c
- Introduce mutex pf_frag_mtx for the above fragment
  storage structures.
- Assert the mutex in storage manipulation functions,
  obtain it in pf_normalize_ip() and in pf_normalize_ip6(),
  when we are dealing with a fragment.
- TODO: lock pf_normalize_tcp_stateful()

Other bits in progress:
- Rename the main pf_task_mtx, to pf_mtx, description
  "pf Giant".
- Introduce rwlock pf_rules_lock, that protects rules.
- Obtain the rwlock in pf_test(), pf_test6().
- Micro-optimise pf_test(), pf_test6() obtaining the pf Giant
  after initial assertions and basic checks.
