Fixes since 0.21.2:

• When an avatar is downloaded, announce the change to the avatar token
  immediately; if the avatar changes from A to B while we're still
  doing the asynchronous file saving, don't set A as the new avatar
  when it has been saved. Regression in 0.21.2. (fd.o #70010, Simon)

• Don't crash if the AccountManager returns an incorrect type for the
  Avatar (fd.o #69849, Simon)

Significant changes since the previous stable branch, 0.20.x:

• tp_connection_get_self_contact() now returns NULL if the contact's
  connection has been invalidated, in order to break a reference cycle

• Avatars are saved to the cache asynchronously

• TpBaseConnection implements SelfID, SelfContactChanged according to
  telepathy-spec 0.27.2

• TpAccount:uri-schemes property, with change notification requiring
  Mission Control 5.15+
