wext: Emit event stream entries correctly when compat.
Three major portions to this change:
1) Add IW_EV_COMPAT_LCP_LEN, IW_EV_COMPAT_POINT_OFF,
and IW_EV_COMPAT_POINT_LEN helper defines.
2) Delete iw_stream_check_add_*(), they are unused.
3) Add iw_request_info argument to iwe_stream_add_*(), and use it to
size the event and pointer lengths correctly depending upon whether
IW_REQUEST_FLAG_COMPAT is set or not.
4) The mechanical transformations to the drivers and wireless stack
bits to get the iw_request_info passed down into the routines
modified in #3. Also, explicit references to IW_EV_LCP_LEN are
replaced with iwe_stream_lcp_len(info).
With a lot of help and bug fixes from Masakazu Mokuno.
