Description:

Initial fix of file transfer by removing extra calls to purple_xfer_set_bytes_sent() and purple_xfer_set_completed(). Also, remove needless member bytes_remaining from PurpleXferPrivate. Works reliably for me on XMPP. However, the redundant purple_xfer_set_completed() calls may be relied upon by other protocols. This needs to be tested. Ok'd by elb. Refs #16001
