Replace the old libusb 0.1 API with libusb 1.0.
- Update device detection and USB transfers.
- Update USB interface and resource handling.
- Use pkg-config to find the library.
- Update build dependencies and installation instructions.
Listing of usb devices with libusb-1.0 is too slow and not usable for
flashing or cold-flashing Nokia N900.
Old libusb (0.1) does not have this problem and works perfectly.
Problem for libusb-1.0 was reported at least two times into libusb-devel
mailing list, but upstream developers are totally ignore it. One message is
in archive: https://sourceforge.net/p/libusb/mailman/message/34985373/
Because of that there is just one option: use tested and working libusb 0.1
library instead some experimental and non-working libusb-1.0.
