Summary:                    [patch] Add support to handle incoming out-of-dialog
SIP NOTIFY requests for "message-summary" event package
Description: 
The existing Asterisk code rejects all incoming out of dialog SIP NOTIFY
requests with a "489 Bad Request" response. This feature adds support for
handling NOTIFY requests with "message-summary" event package. This will
allow third party telephone switches and voicemail systems to set and clear
MWI lamps to SIP phones configured on Asterisk.

With this change, Asterisk code will not reject an incoming out of dialog
NOTIFY
request by default. It will examine the "Event" header and "Content-Type"
header
before sending a response. If the event package is "message-sumary" and
the content type is "application/simple-message-summary", then Asterisk
will process the request further. Asterisk will attempt to ascertain if the
intended 
destination has subscribed for "message-summary". If an active
subscription is 
found, a NOTIFY request will be generated based on the subscription
dialog. If 
no subscription is found, then an unsolicited NOTIFY request will be
generated. 
In both cases, a successful response to the original NOTIFY requested will
be 
sent. Asterisk will continue to reject the request with 489 "Bad event"
for all 
out of dialog NOTIFY request with event package other than
"message-summary. 
Additionally, it will reject the NOTIFY request with 400 "Bad request" if
the 
message body is not formatted per RFC 3842. On receiving a NOTIFY request
for an
extension that is not currently registered, Asterisk will respond with 404
"Not 
found".

  Add support for receiving unsolicited MWI NOTIFY messages.
  
  This change adds a configuration option to SIP peers,
unsolicited_mailbox, which
  configures a virtual mailbox to use for received new/old MWI
information. This
  virtual mailbox can then be used by any device supporting MWI.
