- reading state save area for every threads takes too long when all
application threads have completed and there are stale ATT events to
process
- on detach gdb seemed to be frozen waiting for ATT event to be handled
- fix is to read state save area once - and check SIP counter for every
thread in ATT bitmask

Single-stepping threads is based on resume() and THREAD_STOPPED events
To speed up single-stepping, stopped threads must be discovered
immediately after resume() is called.
This change is adding ATT scan and event generation in resume()

- refactor unit tests - do not start async thread in ults when not
needed , use synchronous read mode instead
