Check for correct state (InferiorStopped).

Use debugger's 'gu' command instead of temporary breakpoint as a
workaround until it is properly supported by the
SetExecutionStatus() API.

this includes:
- move the gdb ownership back to the engine (thus strip down the
  adaptors as far as possible)
- make gdb startup synchronous
- make adapter shutdown synchronous
- fix the state transitions relating to shutdown

As otherwise breaking when attaching to running processes
does not work as the startup trap is not received.

... with an event loop with disabled user input to keep
the GUI alive.

after refactoring the trk adapter startup, the split was not necessary
any more. in fact, it seemed fairly arbitrary at this point.

- Turn off initial breakpoint when attaching (terminal) and
  additionally ignore it before the first startup complete
- Refuse to step  the artifical thread created when
  interrupting
- If possible, switch to thread 0 when interupting (do not
  use artificial thread)
- Ignore non-fatal exceptions in dumper calls (stray Startup-
  complete-traps)
- Use right thread for dumper call loading
- Rename windows exception code enumeration
- Turn off modification off watch-data children by setType,
  show empty lists correctly.
- Verbose warnings about inserting invalid watch data.

Add utility to figure out DLL/Product versions.

Use new call syntax of 6.11. for dumper call loading. Execute
Dumpers in a single thread (current) if at all possible (not
in some WaitFor or artificial break thread). Show one more
frame in threads view if it is FastCallReturn. Fix step into
(ignore one event), log some more exceptions. Generally log
exceptions to the debugger windows to be able to see stuff
like DLL missing, etc.

Also move Designer::Internal::FormWindowEditor ->
Designer::FormWindowEditor.

Simplify & Generalize stepping code, introduce stubs for reverse
debugging. When user switches to another thread than the
event-triggering one in a stopped inferior, explicitly tell
the engine to continue that one.

Improve fixDumperResult to fix missing types (out of scope items)
and call it from expandPointerDumpable.

Remove unused exec functions, replace by calls to the respective
stepExec/nextExec, which sets the code level automagically
according to the OperateByInstruction action.

Adapt to new state model, make sure session is always cleaned
when invoked from processExited event handler, remove calls
to DebuggerManager::notifyXX().

For device debugging. Move both from namespace
Debugger::Internal to Debugger, export them, give
DebuggerManager a static instance().

Intergrate per-engine state tracking with the global running/stopped state.

By fixing a bug in CdbDebugEnginePrivate::setCodeLevel.

- Watchwindow: Do not open Address dialog if menu is canceled (act = 0
  matching the unitialized unknown memory action)
- Actually pass the address of the dialog to the agent
- Make the "Open Memory editor..." action always visible to be able to
  look at const char *x pointing at y
- Improve the address dialog with checking and dialog button box
- Explicitly pass the quint64 around
- Translate & purge

It is replaced by a real editor in e82d6c7b.

"Stepping instruction wise" and "display disassembler" mode is now toggled by a
single action. This also allows to re-use F10 and F11 as keyboard shortcut.

Missing: caching of disassembler output, removal of old disassembler view.

Show the current number base in the view.

Fix "displayedtype" in CDB, display it elsewhere.
Log debugger settings in DebuggerManager startup.

Do not add all image paths (from different projects), keep a
base path and add current.
