b88c4aa75e Add move-function for sc_usb_device 
Add a function to "move" a sc_usb_device into another instance.

This will avoid unnecessary copies.

b0e04aa327 Remove log_libusb_error() 
This helper did not help a lot, and prevented the client to choose the
log level and the prefix error message.

1a03206e36 Detect USB device disconnection 
The device disconnection is detected when the video socket closes.

In order to introduce an OTG mode (HID events) without mirroring (and
without server), we must be able to detect USB device disconnection.

This feature will only be used in OTG mode.

8fc9dca8cb Make serial optional to find USB devices 
If no serial is provided, then list all available USB devices (which can
be open and having a serial).

1c17f57c10 Find a list of devices instead of a single one 
Several devices may match the requested serial, but above all, this
paves the way to list all devices (when no serial is provided).

d8b37fe189 Wrap libusb_device 
Introduce a structure to wrap a libusb_device and expose its descriptor
data read during discovery.

0ee9e2ff51 Expose function to find a USB device 
The device was automatically found by sc_usb_connect(). Instead, expose
a function to find a device from a serial, and let the caller connect to
the device found (if any).

This will allow to list all devices first, then select one device to
connect to.

1ab3692f3d Add util function to read USB descriptor string 
Use it from accept_device() to simplify (at the cost an additional
allocation for each serial, but it is not important).

It will also be useful in other functions in further commits.

bbef426a4b Split USB initialization and connection 
This will allow to execute other USB calls (retrieving the device list
for example) before connecting to the selected device.

b779eca8d3 Remove libusb_device field 
It is possible to retrieve the device instance from the handle via
libusb_get_device(), so we don't need to reference the device one more
time.

1d6f9952ee Extract USB handling from AOA

Extract USB-related code to a separate file and structure.
