969678c098 tools: ffs-aio-example: use endpoint addresses from descriptors
This makes examples more platform independent and more compatible with
USB standard, as endpoint addresses in given interface may differ
between hardware platforms or even between configurations in single
USB device.

b34e08d5c7 tools: usb: aio example applications
This patch adds two example applications showing usage of Asynchronous I/O API
of FunctionFS. First one (aio_simple) is simple example of bidirectional data
transfer. Second one (aio_multibuff) shows multi-buffer data transfer, which
may to be used in high performance applications.

Both examples contains userspace applications for device and for host.
It needs libaio library on the device, and libusb library on host.
