* nscd/nscd-client.h (libc_locked_map_ptr): Add new first parameter, used as class for definition. * nscd/nscd_getpw_r.c: Adjust for libc_locked_map_ptr change. (pw_map_free): Ensure no crash after memory is freed. * nscd/nscd_getgr.c: Likewise. Make map externally visible. * nscd/nscd_gethst.c: Likewise. * nscd/nscd_getai.c: Use map from nscd_gethost.c. * nscd/nscd_initgroups.c: Use map from nscd_getgr.c.
