- while resuming threads - after checking threads stopped immediately
check for FE bit, if set do not generate thread stop event
- if PageFault occured, report stop event based on pagefault event

- check threads with attention state before reading SR_IDENT
- memory read is costly, for threads already in stopped state
there is no need to read sr_ident and check thread state again
- single stepping one thread performance is substantially improved,
by the factor of 6x

- 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

- before marking interrupt request check exception reason. If there is
exception other than forced exception or forced external halt treat
thread as stopped and generate distinct event for it.

- threads with pending events cannot be resumed by resume(all) as they
they were not yet discovered by debugger as stopped.
- set reportAsStopped when THREAD_STOPPED event is read
- when resuming, only resume a thread when it was reported

- check threads with ATT only when more than one thread is resumed
- if single thread is resumed - check only that thread
- delay thread state check - allowing thread to reenter SIP

- make sure to capture all threads after interrupt, also those that
could be lagging to enter SIP

- read/write registers/memory only allowed for threads reported as
stopped by events
- threads newly stopped, accidentally, that are resumed immediately
are not allowed register/memory access

Register read/write implementation was unnecessarily checking magic values
which were taking significant time. By removing those checks, register
access is speed-up by a factor of 3.

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()

- getInternalEvent() should wait on cv that is notified when new event is
read
- this change speeds up application execution under debugger
- refactor unit tests - do not start async thread in ults when not
needed , use synchronous read mode instead
