1) Break the core cryptography functions out into libaxolotol.
2) The objective for this code is a Java library that isn't
dependent on any Android functions. However, while the
code has been separated from any Android functionality,
it is still an 'android library project' because of the
JNI.
Currently the order of numbers is times contacted -> displayName ->
phone type (mobile vs. home, etc.). This adds whether the number has
been saved as the default number for a contact to sort numbers belonging
to the same contact.
Fixes#580
1) Updating a group without changing the avatar will keep that
avatar
2) Prohibit adding non-push users to an existing push group
3) Add Android contacts to the same database. Takes a small amount
more time and memory, but allows queries to not be a hack, and
enables us to dedupe numbers in JB and higher devices.
// FREEBIE
* unify single and multi contact selection activities
* follow android listview design recommendations more closely
* add contact photos to selection
* change indicator for push to be more obvious
* cache circle-cropped bitmaps
* dedupe numbers when contact has multiple of same phone number
// FREEBIE
1) Move all the crypto classes from securesms.crypto.
2) Move all the crypto storage from securesms.database.keys
3) Replace the old imported BC code with spongycastle.
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.
