Debugger[TCF TRK]: Adapt to TCF TRK 4.0.5

- Parse/Format errors correctly (long codes)
- Use standard 'Registers' service, fake 'getm' as long as it is
unimplemented
- Use 'Registers|getChildren' for each thread to activate the context
and use the names obtained from there instead of hardcoded register
names
