PS. Of course another approach is to use two threads one for ep0 and the
other for transfers. Yet another, is to add AIO to ep0 in the kernel.

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.
