[SCSI] libfc: add fc_fill_reply_hdr() and fc_fill_hdr()
Add functions to fill in an FC header given a request header. These reduces code lines in fc_lport and fc_rport and works without an exchange/sequence assigned. fc_fill_reply_hdr() fills a header for a final reply frame. fc_fill_hdr() which is similar but allows specifying the f_ctl parameter. Add defines for F_CTL values FC_FCTL_REQ and FC_FCTL_RESP. These can be used for most request and response sequences. v2 of patch adds a line to copy the frame encapsulation info from the received frame.
