  -----------
  mid_registrar: Fix mem management bugs around "max contacts"

* avoid UAF of the @uc pointer during iteration
* fix logic so that the current @c cannot be freed by trim_contacts()
    itself, yet again leading to UAF type of bugs

usrloc: Fix rare memleak edge-case

  Log Message:
  -----------
  registrars: Allow accepting Re-REGISTERs with equal CSeq

New module setting for both registrar and mid-registrar which controls
the policy on handling same Call-ID REGISTERs, with the same CSeq.

    modparam: allow_dup_cseq
    default:  false (100% backwards-compatible)

Ultimately, this boils down to a trade-off between interoperability and
RFC strictness.  More info in the modparam documentation.
