to be able to put already read blob_id into parameter instead of creating new 
blob_id.

  I tested with attached application and got this:

tx1: blob id = 80:1
tx2: blob id = 80:2
tx1: blob id = 80:3

Which seems to be logical, because engine cannot tell whether blob id it has on input comes from current record or other record in other table. Comment in BLB_move confirms that:

// If the source is a permanent blob, then the blob must be copied.
// Otherwise find the temporary blob referenced.
