melifaro 881c9e28bf Simplify filling sockaddr_dl structure for if_resolvemulti() ... callback providers. link_init_sdl() function can be used to fill most of the parameters. Use caller stack instead of allocation / freing memory for each request. Do not drop support for extra-long (probably non-existing) link-layer protocols by introducing link_alloc_sdl() (used by if_resolvemulti() callback) and link_free_sdl() (used by caller). Since this change breaks KBI, MFC requires slightly different approach (link_init_sdl() auto-allocating buffer if necessary to handle cases with unmodified if_resolvemulti() callers).
