Obtain remote device's own phonenumber from MessagesListing

MAP profile does not provide explicit commands to obtain the phone
number of the connected remote device. The remote device's own phone
number is needed to help Messenger apps to properly stitch together
conversation threads, particularly in group messaging.

Parsing the recipients of a received group MMS for the remote device's
own number is problematic because the MMS specs do not specify any
standards regarding the To: and Cc: fields of a MMS.

Instead, this CL obtains the own phonenumber from  (1) originator
(From:) field of messages in the SENT folder; (2) recipient (To:)
field of SMS messages (ignoring MMS) in the INBOX folder.

MessagesListing contains metadata of messages in a folder, including
phone numbers of recipients and originators. However, MAP profile
lists recipient metadata as optional, HCI logs show most major phones
do provide it. If the first message doesn't have it, the CL increasingly
requests more messages until a number is found.
