Fix a race condition in xfer abort.  Derived from a FreeBSD patch.
An xfer could be aborted twice (which means that the second abort might
access deallocated memory).  This happened when an xfer timed out and
the timeout started an abort.  While that abort was taking place the
xfer could be cancelled (usually by closing the pipe), causing a second
abort to begin.
This is now handled by having flags indicating the abort state of an xfer.
Hopefully this will fix the occasional crashes when printing.
