Add the ability to detect and print the USB speed as "super-plus" if/when
the kernel reports that speed.

testusb' application which uses 'usbtest' driver reports 'unknown speed'
from the function 'find_testdev'. The variable 'entry->speed' was not
updated from the application. The IOCTL mentioned in the FIXME comment can
only report whether the connection is low speed or not. Speed is read using
the IOCTL USBDEVFS_GET_SPEED which reports the proper speed grade. The
call is implemented in the function 'handle_testdev' where the file
descriptor was availble locally. Sample output is given below where 'high
speed' is printed as the connected speed.

Currently, default vary will not accomodate superspeed endpoints
causing unexpected babble errors in the IN direction. Let's update
default 'vary' parameter so that we can maintain a "short-less"
transfer as hinted at the comment.

For ctrl out test, it needs length > vary, so in order to run it with
default parameters, we do this change.

Commit 8a424bf40d (tools/usb: remove last USBFS
user) removed 'usbfs' files from the source but retained mentions of 'usbfs'
all over the place, most importantly in the misleading error messages printed
in case USB device files are not there. Remove all the mentions of 'usbfs'
for good now!

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.

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/>.
