Dmitry Borisov f15de15554 [ISAPNP] Fixes and improvements for IRP handling
- Implement device removal.
- Finish the Read Port special handling
  introduced in 21514e473f.
- Gracefully handle low memory situations.
- Implement IRQ translator.
- Correctly stub power IRP handling.
- Remove unneeded dispatch routines; implement WMI IRP handling.
- Do not handle requests like WRITE_CONFIG.
- Add a signature member to device extensions to make checks clearer.
