History
John Baldwin eb5a1e8f38 This patch fixes two bugs in sglist(9) and improves robustness of the API via 
better semantics if a request to append an address range to an existing list
fails.
- When cloning an sglist, properly set the length in the new sglist instead of
  leaving the new list empty.
- Properly compute the amount of data added to an sglist via
  _sglist_append_buf().  This allows sglist_consume_uio() to properly update
  uio_resid.
- When a request to append an address range to a scatter/gather list fails,
  restore the sglist to the state it had at the start of the function call
  instead of resetting it to an empty list.
