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.

this drastically improves the usefulness of the debugger output window
by making internal and external messages appear in sync.

Add a configuration checking method to the Debugger manager,
depending on toolchain, wire it to the engines.
Check that in the debugger run controls.

Add a convenience method to ICore that shows a warning
message with a "Settings" button, pointing the user
to a configuration error on a settings page.

Remove leftovers of the dumper parser.
