usb: usb3 streams support for usb-host and usb-redir
usb: xhci and mtp bugfixes.

# gpg: Signature made Mon 26 May 2014 09:44:09 BST using RSA key ID D3E87138
# gpg: Can't check signature: public key not found

* remotes/kraxel/tags/pull-usb-7:
  usb-host-libusb: Set stream id when submitting bulk-stream transfers
  usb-host-libusb: Add alloc / free streams ops
  usb-host-libusb: Fill in endpoint max_streams when available
  usb-redir: Add support for bulk streams
  usb-mtp: handle usb_mtp_get_object failure
  usb-mtp: handle lseek failure
  usb-mtp: use bool to track MTPObject init status
  xhci: add xhci_get_flag
  xhci: add endpoint cap on express bus only
  xhci: child detach fix
