USB Improvements status report 6

[Sylvestre Gallon]

Hi,

Done for this week :

- Replaced libusb list by queue(3).
- Added a support for queueing multiple transfers on the same endpoints.
- Fixed some bugs spotted by Hans Peter Selasky.
- Added support for big transfers.
- Removed some errors spotted by Clang/LLVM

Now libusb seems to work fine with control bulk and isochronous
endpoints. Isochronous transfers have not been tested yet.

If Hans Petter is Ok I will not work on libusb for next week and
focus my mind on USB Function.

Cheers,
