s3:winbindd: factor winbindd_sids_to_xids into external and internal part

- external part takes winbindd request/reponse structs (with sid strings)
- internal part takes sid lists

The new internal part implements functions wb_sids2xids_* that are
moved into the new module wb_sids2xids.c.

The purpose of this change is to use wb_sids2xids in winbindd_sid_to_uid
and winbindd_sid_to_gid instead of the currently used wb_sid2uid and wb_sid2gid.
We should just have one code path into id mapping and not several that behave
differently.
