37e47d5cfe usb: usbip tool: Fix get_nports()
The commit 0775a9cbc694e8c72 ("usbip: vhci extension: modifications
to vhci driver") introduced multiple controllers, and nports as a sys
file, and claimed to read the nports from it, but it didn't.

In addition, the get_nports() has been so wrong that even with 8 port
lines for instance, it gets 7 (I am guessing it is due to a '\n' mess).
Nevertheless, we fix it by reading the nports attribute.

e5dfa3f902 usbip: Fix potential format overflow in userspace tools
The usbip userspace tools call sprintf()/snprintf() and don't check for
the return value which can lead the paths to overflow, truncating the
final file in the path.

More urgently, GCC 7 now warns that these aren't checked with
-Wformat-overflow, and with -Werror enabled in configure.ac, that makes
these tools unbuildable.

This patch fixes these problems by replacing sprintf() with snprintf() in
one place and adding checks for the return value of snprintf().

7b3f74f7e0 usbip: tools: Add vudc backend to usbip tools
Adds an equivalent of usbip_host_driver for the vudc. Most
of the code is already shared, but this adds some vudc specific
code for getting information about devices.

3391ba0e27 usbip: tools: Extract generic code to be shared with vudc backend
Extract the code from current stub driver backend and a common
interface for both stub driver and vudc. This allows to share most
of the usbipd code for both of them.
