Add hotplug support.

The internal API is changing as follows:
 - Adding two new functions. usbi_connect_device, and usbi_disconnect_device.
   Backends must call these functions to add them to the context's device list
   at one of two places: initial enumeration (done at init), and on device
   attach and removal. These functions need to be called once per context.
 - Backends that support hotplug should not provide a get_device_list funtion.
   This function is now deprecated and will likely be removed once all backends
   support hotplug.

The external API is changing as follows:
 - Two new functions have been added to register and deregister callbacks for
   hotplug notification: libusb_hotplug_register_callback(),
   libusb_hotplug_deregister_callback(). Hotplug callbacks are called by
   libusb_handle_events(). Details of the new API can be found in libusb.h.
 - A new capability check has been added to check for hotplug support. See
   LIBUSB_CAP_HAS_HOTPLUG.

Aa suggested by Xiaofan add new example has been added to show how to use
the new external hotplug API. See examples/hotplugtest.c.
