Hi,
This is a resend of [0] trying to reconnect drivers gracefully in case of
a protocol removal failure.

Changes since v1:
- Fix an existing memory leak when uninstalling a protocol.  The opened
  protocol information was never released
- Drop a patch that was incorrectly trying to free protocols on the handle
  that were not associated with the driver being released
- Rewrite the sefltests and instead of installing a second driver handle
  on the controller handle, force the controller to return EFI_DEVICE_ERROR
  on the first removal. When that happens all the children,  that are
  disconnected before the controller, must be reconnected
- Reconnect all controllers on the handle if after disconnecting drivers
  and closing protocols opened by GET_PROTOCOL, TEST_PROTOCOL, HANDLE_PROTOCOL
  opened protocols are still present in the handle
