Basically remove unneeded code. Since that 'continue' is at the end
of the for() there's no need for it.

In commit fb28d58b ("USB: remove CONFIG_USB_DEVICEFS") USBFS got
removed. Since it is gone we can stop using it in testusb and try udev
nodes right away.

The testusb.c tool has support for looping forever implemented, which
may be useful for stress test, yet it is not exposed to the user, so
even though the code is there, it cannot be used.  This commit adds
"l" to the set of options handled by the application which enables
the feature.

Also, I collate help information for each command line option to make
it easier to use for novice.

As real device-nodes managed by udev whose nodes lived in /dev/bus/usb
are mostly used today, let testusb tool use that directory as one default
path make tool be more convenient to use.

The out functions should only handle actual available data instead of the complete buffer.
Otherwise for example the ep0_consume function will report ghost events since it tries to decode
the complete buffer - which may contain partly invalid data.

Use the header file in tools/include instead of duplicating the endian
functions.

The m.nazarewicz@samsung.com email address is no longer valid,
so this commit replaces it with mina86@mina86.com which is
employer-agnostic and thus should be valid for foreseeable
feature.

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).

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/>.
