When compiling this program the functionfs.h header cannot be found, producing:
ffs-test.c:40: fatal error: linux/usb/functionfs.h: No such file or directory
This patch also fixes the following warning:
ffs-test.c:453: warning: format ‘%4d’ expects type ‘int’, but argument 3 has type ‘size_t’

Enhance the test script to call the new tests added to usbtest
in order to detect host controllers that don't accept byte
aligned DMA.
The unaligned tests are called after their aligned
equivalents but for fewer iterations (since alignment
failure is generally immediate).

This patch just adds the script available at
http://www.linux-usb.org/usbtest/test.sh as is.

The FunctionFS gadget may provide the source/sink interface
not as the first interface (with id == 0) but some different
interface hence a code to find the interface number is
required.
(Note that you will still configure the gadget to report
idProduct == 0xa4a4 (an "echo 0xa4a4
>/sys/module/g_ffs/parameters/usb_product" should suffice) or
configure host to handle 0x0525:0xa4ac devices using the
usbtest driver.)

The testusb program just issues ioctls to perform the tests
implemented by the kernel driver. It can generate a variety
of transfer patterns; you should make sure to test both regular
streaming and mixes of transfer sizes (including short transfers).
For more information on how this can be used and on USB testing
refer to <URL:http://www.linux-usb.org/usbtest/>.

This adds an example user-space FunctionFS driver which
implements a source/sink interface used for testing.
