Import fuse-mp3fs-0.91 as wip/fuse-mp3fs.
This is the version that was in filesystems/fuse-mp3fs for a short while
with two additional patches.

MP3FS is a read-only FUSE filesystem which transcodes audio formats
(currently FLAC) to MP3 on the fly when opened and read. This was
written to enable using a FLAC collection with software and/or
hardware which only understands MP3.

It is also a novel alternative to traditional MP3 encoder applications.
Just use your favorite file browser to select the files you want
encoded and copy them somewhere!
+ fuse-mp3fs.
Multiple problems on NetBSD:
* does not parse options correctly:
  "-b 128", "--bitrate=128" not recognized
  "-h", "-V" cause core dumps
* does not handle two path arguments like usage suggests
  mp3fs /a /b
  errors out; one of the patches works around this, but that's
  not a solution and I don't know how it's supposed to work
* after working around these problems, does not transcode
  files -- just copies flac files
