// "Default migrations" are used to migrate previous setting defaults to new
// values. If we simply change the default in the metadata, it might cause
// problems if the user has never previously set the value.
//
// It happened for example when changing the "sync.target" from 7 (Dropbox) to 0
// (None). Users who had never explicitly set the sync target and were using
// Dropbox would suddenly have their sync target set to "none".
//
// So the technique is like this:
//
// - If the app has previously been executed, we run the migrations, which do
//   something like this:
//     - If the setting has never been set, set it to the previous default
//       value. For example, for sync.target, it would set it to "7".
//     - If the setting has been explicitly set, keep the current value.
// - If the app runs for the first time, skip all the migrations. So
//   "sync.target" would be set to 0.
//
// A default migration runs only once (or never, if it is skipped).
//
// The handlers to either apply or skip the migrations must be called from the
// application, in the initialization code.
