* Add hotplug support.Nathan Hjelm2013-05-151-0/+96
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.
