The commit introduces a new, generic, Alarm class. The class lets you to schedule functions (callbacks) that will execute after a predefined timeout. Once scheduled, you can cancel and reset a callback, given the timeout hasn't expired yet. The alarm class worker thread that sleeps until the next timeout expires. When the thread wakes up, it checks for all the callbacks that have expired and calls them in order. Because the callback is called from the worker thread, the only guarantee is that a callback is called no sooner than the timeout. A long running callback could potentially block the worker threads and delay other callbacks from getting called. I intentionally kept the implementation as simple as possible while addressing the needs for the use case of coalescing progress events as discussed in [1]. If we want to rely on this somewhere else, we can reassess whether we need to address this class' limitations. [1] https://discourse.llvm.org/t/rfc-improve-lldb-progress-reporting/75717/
