1) Refactor recipient class to support asynchronous loading operations.
2) Refactor recipient factory to simplify recipient access.
3) Consoliate everything into one recipient provider that is capable of
doing async lookups and intelligent caching.
Mostly, the inheritance graph for MessageRecord/MmsMessageRecord was
all messed up, and each class was overloaded for things it shouldn't
have been.
1) Broke MessageRecord/MmsMessageRecord up into: DisplayRecord, ThreadRecord,
MessageRecord, SmsMessageRecord, NotificationMmsMessageRecord, and
MediaMmsMessageRecord.
2) Updated all the adapters/views to keep pace with that change.
1) Add >= ICS profile support (the system-supported "me" contact).
2) Improve <= Gingerbread support for me contact by auto-detecting
contacts that have the same number as the SIM card.
3) Tie in identity key import/export support to the "me" contact.
4) Don't display a "me" selection option in preference if it can
be auto-detected.
5) Refactor out the ContactAccessorNewApi back into the base class.
The 1.X Android versions don't have the 2.X VERSION_CODE
symbols, so comparing against them in order to make 1.6
choices will throw runtime exceptions.
