- 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

Compile fix. In mingw32 there is a sys/time.h with struct timeval. Someone under cygwin should test.

Refs: #900 #920 #1031

 * 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.

Now it really seems to work.

Really fixes #1051

Fixes #1051

Add option to specify which muxer we want to use in ffmpeg (ie: #std{mux=ffmpeg{mux=flv}...) Still seems kind of broken as the resulting file can't be demuxed by vlc/libavformat. Looks like the video and audio codec aren't identified correctly in the ffmpeg muxer. Must be some error in mux.c i guess.

That being said, I either don't understand sout chain (likely) or
it is plain broken (unlikely) but I can't seem to pass parameters
to the access output.

Fix #1048... kind of. Should the rc interface be able to accept more than 1 connection ? and accept tcp connections + stdin commands ? (currently only 1 connection can be active)

(this is a revert of ffmpeg [7589])
