Patch submitted by hoefnix. Ref. https://groups.google.com/d/msg/minix-dev/sHQDVJRyx1c/eJjrYOqk5bgJ Change-Id: I2fcdf4cf119ef252ccc7df06849baf37ffd08440
This Shared Folders File System library (libsffs) now contains all the file system logic originally in HGFS. The actual HGFS server code is now a stub that passes on all the work to libsffs. The libhgfs library is changed accordingly.
