  Improve handling of REGISTER requests with multiple contact headers.

  The changes here attempt to more strictly follow RFC 3261 section 10.3.
  Basically the following will now cause a 400 Bad Response to be returned, if:
  - multiple Contact headers are present with one set to expire all bindings ("*")
  - wildcard parameter is specified for Contact without Expires header or Expires
    header is not set to zero.
