callstack: Add synchronization on fields in data provider

Commit ef3c56e87c797f7a41e5d717fdc5b37266f95a60 removed the locking from
the data provider, but it was not entirely unnecessary. Some
synchronization is required on the fIdToCallstack field to ensure there
are no ConcurrentModificationException, but locking is introduced in
micro-dose only where necessary.
