**************************************************************************
*  Mnemonic: SIterm
*  Abstract: This routine will terminate a session based on the tp_blk
*            that is passed into the routine. The transport session block
*            is released and removed from the ginfo list. The session is
*            terminated by issuing a t_unbind call (if the unbind flag is
*            on in the tpptr block), and then issuing a t_close.
*  Parms:    gptr - Pointer to the global information block
*            tpptr - Pointer to tp block that defines the open fd.
*  Returns:  Nothing.
*  Date:     18 January 1995
