[PATCH v3 0/4] usbgadget: add support for USB mass storage gadget

[Ahmad Fatoum]

v2 -> v3:
  - rebase on v3 of the preparatory system partitions series
  - have usbgadget -S '' fallback to use $global.system.partitions
  - do file_list_detect_all at gadget instantiation time

v1 -> v2:
  - rebase on top of new bthread API
  - drop blocking fallback implementation; we now have bthreads
    everywhere
  - reuse $global.system.partitions instead of creating even
    more autostart variables
  - fix assert_command_context to actually do what the
    commit message said

Ahmad Fatoum (4):
  bthread: implement basic Linux-like completion API
  slice: reschedule bthreads doing File I/O in command context
  usbgadget: refactor usbgadget_register to accept array
  usbgadget: add support for USB mass storage gadget
