Used to return well known directories such as Trash, Desktop, etc. from different
file systems.
There is quite a complicated logic behind finding/creating a Trash directory
and you need to be aware of some implications:
Finding the Trash the first time when using the file method may be pretty
expensive. A cache file is used to store the location of that Trash file
for next time.
If ceate_if_needed is specified without find_if_needed, you may end up
creating a Trash file when there already is one. Your app should start out
by doing a gnome_vfs_find_directory with the find_if_needed to avoid this
and then use the create_if_needed flag to create Trash lazily when it is
needed for throwing away an item on a given disk.
