Alan Stern 01c6460f96 USB: usbfs: add USBDEVFS_URB_BULK_CONTINUATION flag
This patch (as1283) adds a new flag, USBDEVFS_URB_BULK_CONTINUATION,
to usbfs.  It is intended for userspace libraries such as libusb and
openusb.  When they have to break up a single usbfs bulk transfer into
multiple URBs, they will set the flag on all but the first URB of the
series.

If an error other than an unlink occurs, the kernel will automatically
cancel all the following URBs for the same endpoint and refuse to
accept new submissions, until an URB is encountered that is not marked
as a BULK_CONTINUATION.  Such an URB would indicate the start of a new
transfer or the presence of an older library, so the kernel returns to
normal operation.

This enables libraries to delimit bulk transfers correctly, even in
the presence of early termination as indicated by short packets.
