Add libusb_has_capability() API function
Since it is currently not planned to change the filename of the libusb
library between libusb-1.0 versions at least on Windows systems it's
important to have a capability API.
Currently there exists only one capability; LIBUSB_CAP_HAS_CAPABILITY,
which tests support for the libusb_has_capability() API.
