JBMR2 runtime restart (system process crash in the sync manager) during setup
The fix is to ensure that all access to SyncStatusInfo and related objects happens
while holding the mAuthority lock or is on a per-thread copy of the objects
Also, includes an unrelated fix for a bug I just noticed in the way
dumpSyncState() prints the periodic sync info
