Rationale: on Android one must use UsbManager, to access any
USB device. As a result, libraries like libusb can only use file descriptors
that are provided by UsbManager.
libusb has an API to use such file descriptors: hid_libusb_wrap_sys_device.
Having hid_libusb_wrap_sys_device currently is the only way to make hidapi
work on Android without root access and without custom Android builds.

When checking the diff, select "Hide whitespace changes" option on Github - makes the diff smaller and easier to read.

I'd appreciate an input from libusb team, if any.

Looks propper to me to support the unrooted way on the hid api too.
I haven't test the hid api for now, so I cannot give any further advices.
