mapping addition. (ga_clone): Just call ga_dup from here. (ga_duplist): New function to duplicate list of struct addrinfo. (ga_echeck): Don't check a_flags, it already happened in cygwin_getaddrinfo. (cygwin_freeaddrinfo): Always call ipv4_freeaddrinfo. (cygwin_getaddrinfo): Use new wincap.supports_all_posix_ai_flags flag rather than wincap.has_gaa_on_link_prefix. Always duplicate WinSock's addrinfo list to a self-allocated list. Handle AI_V4MAPPED for pre-Vista platforms supporting getaddrinfo. * wincap.h (wincapc::supports_all_posix_ai_flags): New element. * wincap.cc: Implement above element throughout. * include/netdb.h: Note how AI_ADDRCONFIG is not supported pre-Vista. Remove superfluous comment.
