[Libguestfs] [PATCH nbdkit incomplete 5/5] plugins: Port some plugins to Windows.

[Richard W.M. Jones]

Now ‘--disable-plugins’ can be removed from the previous commit to
enable some plugins and run them under wine:

  sudo dnf install mingw64-gcc mingw64-dlfcn \
                   mingw64-gnutls mingw64-xz mingw64-zlib
  mingw64-configure
  make
  wine ./server/nbdkit.exe -fv \
       ./plugins/memory/.libs/nbdkit-memory-plugin.dll size=1M
