Addendum to commit baa47fa5e.
Similarly to what was originally done, have KdbpCliInterpretInitFile()
parse the KDBinit file by breaking back into the debugger.
But contrary to before, replace the deprecated call to KdbEnter() by
a standard DbgBreakPointWithStatus(DBG_STATUS_CONTROL_C) . This allows
KdbEnterDebuggerException() to do the KdbpCliInterpretInitFile() call.
Additional fixes and improvements:
- Run KdbpCliInterpretInitFile() in full KDBG environment (interrupts
disabled, modified IRQL, own stack), like the usual interactive loop.
- The KDBinit data buffer must be in non-paged pool.
- Demote the "Could not open KDBinit" error to a DPRINT, so that it
doesn't pollute the debug log when the KDBG init function is called
early (before the storage stack is initialized), or if the file
doesn't exist -- since this is an optional feature.
