r11782: - make the TID 32bit in the smbsrv_tcon structure, as SMB2 uses
them - add a idtree_limit to the tcons substructure of smbsrv_connection this controls what the highest TID is we give away to the client it's UINT16_MAX (0xFFFF) for the SMB protocol metze (This used to be commit f3bf5a2c0947e33d4167fa4fa290968204a826e8)
