libusb: rename bNumDeviceCapabilities to bNumDeviceCaps for compatibility with libusb

THe member bNumDeviceCapabilities is referred to as bNumDeviceCaps in
the upstream libusb project.

To improve compatibility, we are renaming the member accordingly.

For backward compatibility, a mocro will be defined to map
bNumDeviceCapabilities to bNumDeviceCaps.

lib: further adoption of SPDX licensing ID tags.

Mainly focus on files that use BSD 2-Clause license, however the tool I
was using mis-identified many licenses so this was mostly a manual - error
prone - task.

The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.

libusb(3): Expose device caps as libusb_bos_descriptor::dev_capability

Some libusb consumers in Linux-land (in this case, libusb4java) expect a
dev_capability member that they can use to enumerate the device
capabilities.

No particular layout is expected of this, just that it can be traversed
using the bLength member until bNumDeviceCapabilities are read and that the
consumer may then use one of the libusb_get_*_descriptor methods to extract
specific (usb 2.0 vs. ss) capability information.
