Feature: USB - Hotplug, mass storage, disconnect callbacks, dynamic device lists

Browse Source

- Add disconnect callback (fnDisconnect) to TUSBDevice for safe unplug handling
- Add HotplugArmed/PortChangePending flags to TUSBHCDriver for deferred
  hotplug processing from ISR context (OHCI RHSC, EHCI PCD, xHCI PSC)
- Implement usb_rescan_port() and usb_check_hotplug() in usbcore
- Add usb_bulk_transfer_wait() with timer-based timeout (bios_data_area)
- Add timer-based timeout to usb_control_msg polling loop
- Replace static device arrays with dynamic linked lists in class drivers:
  usb_keyboard (KeyboardList), usb_mouse (MouseList), usb_storage (StorageList)
- Add 3-strike fail-count self-deactivation in keyboard/mouse poll loops
- Add unload() disconnect handlers for keyboard, mouse, and storage drivers
- Implement USB Mass Storage BOT driver (usb_storage.pas):
  CBW/CSW transport, SCSI INQUIRY/READ_CAPACITY/READ10/WRITE10,
  storagemanagement integration with read/write callbacks
- xHCI: acknowledge port status change W1C bits in event handler
- Integrate usb_check_hotplug + poll_keyboards/poll_mice into kernel main loop
