[ion] 24986: - Fix some bugs in NtWaitForDebugEvent which caused debug events to be sent in the wrong order and also more then one event to be sent at the same time (and thus some events skipped). - Test app now properly receives the "create process" event along with valid process/thread handles and the image base. No file handle sent yet because of the I/O Manager File Object bug. - There's still a bug in NtContinueDebugEvent due to wrong Client IDs being sent.

[ion] 24981: - Forgot to actually initialize Dbgk during system initialization, so any API would crash. - Fix some stupid bugs in NtCreateDebugObject. - Add tracing framework and add tracing to all of debug.c. - Dbgk *almost* works: http://www.tinykrnl.org/dbgworking.png. Here I attach to services.exe and the kernel is sending notifications for all threads and DLLs loaded.
