[Flac-dev] Adding support for .w64 (wave64) format

[Brian Willoughby]

I realize that it isn't much of an improvement, but AIFF supports 4GB  
recordings, and flac is compatible with this.  Being an avid "taper"  
myself, I have, on many occasions recorded up to this limit, and I  
always back up my original recordings using flac.

W64 support is more than welcome, but AIFF support gets you twice the  
length right away.

Our DAW REAPER (www.reaper.fm) supports W64 as well. We'd be happy to
share our W64 reading/writing implementations if someone wishes to
integrate them into flac...
