Make synchronous transfer APIs robust against signal interruption

libusb_control_transfer and libusb_bulk_transfer are designed to be
synchronous such that control is not returned until the transfer
definitively succeeds or fails.  That assumption is violated if a signal
interrupts these functions because there is no way for the application
to continue waiting for the transfer without resubmitting it.  This

a signal interruption.

Linux: Fix race condition in cancel_bulk_transfer()

This fixes a race condition in cancel_bulk_transfer().  In the old
version, awaiting_reap and awaiting_discard are incremented in
cancel_bulk_transfer() and decremented in handle_bulk_completion().
However, since these events may take place in two different threads,
these variables may reach zero before all URBs have been canceled,
triggered spurious callbacks and duplicate frees.

This changes the logic to use a single variable "num_retired" to replace
both awaiting_reap and awaiting_discard.  num_retired is incremented
only in handle_bulk_completion() and thus there is no race.  The handler
will know that all URBs have been canceled when num_retired becomes
equal to num_urbs.

This change also simplifies a great deal of the logic in both functions
and is a net reduction in the amount of code.

Note that some variables such as "reap_action" probably need to still be
