- getaddrinfo.c: use Win32 shim functions to load getnameinfo/getaddrinfo/freeaddrinfo on first call, cleaner than a bunch of if/else in user functions
- announce.c: freeaddrinfo -> vlc_freeaddrinfo

 * Fix ffmpeg muxer. (flv muxing now works with ./vlc  --sout "#transcode{vcodec=FLV1,acodec=mp3}:std{mux=ffmpeg{mux=flv},access=file,dst=test.flv}" -vvv --color ~/media/pinball-bit-rate-vbr-peak.wmv -I dummy) Include 2 hacks ... if someone has a better way to do it feel free to do so.
 * Remove a bunch of trailing white spaces.
