Add the new gadget function for 9pfs transport. This function is
defining an simple 9pfs transport interface that consists of one in and
one out endpoint. The endpoints transmit and receive the 9pfs protocol
payload when mounting a 9p filesystem over usb.

v3 -> v4:
- implemented conn_cancel
I tried this scenario:
1) run all the components and have 9pfs up and running
2) stop the forwarder
3) umount -f at the gadget side - this indeed succeeds now in v4
4) start the forwarder again
5) mount at the gadget side - this hangs.
Did this scenario work for you?
I actually tested this exact scenario. So this is
suprising. I will try this again just to be sure
that I did send the latest version.
My latest testsetup included the dummy_hcd. Did you test on real hardware?
Yes, I did.
I just also tested this again on real hardware. With the imx6 chipidea
udc I indeed see that this is stuck after the first round of mount and
remount. With the musb core on the beaglebone this seems to be fine.
While debugging this I also ran into some shutdown issues and lockdep
issues I see because the complete handler is possible to be resumed
immedeatly on musb, which is odd. However I fixed/fix them and send an
v5 afterwards.
Regarding the hang on the imx6, which hardware did you test this on?
