Handle all known transfer/pipe errors.

  * Remove `PipeErr::Other`.
  * Add more variants to `PipeErr`.
  * Integrate `is_transfer_complete` into `dispatch_result` and
    simplify.
  * Cache volatile `intflag` on entry to `dispatch_result` to ensure
    consistent handling.
  * Clear fail/perr `intflag` bits in `dispatch_result`.
