This simply creates and raises the dialog, and returns.
When the user hits OK or Cancel, the callback will be run.
prompt_string: the window title, or whatever.
default_path: the directory which should be shown to the user by default.
This may be 0, meaning "use the same one as last time." The pathname
will be in URL (Unix) syntax. (If the FE can't do this, or if it
violates some guidelines, nevermind. Unix uses it.)
file_must_exist_p: if true, the user won't be allowed to enter the name
of a file that doesn't exist, otherwise, they will be allowed to make
up new names.
directories_allowed_p: if true, then the user will be allowed to select
directories/folders as well; otherwise, they will be constrained to
select only files.
The dialog should block the user interface while allowing
network activity to happen.
The callback should be called with NULL if the user hit cancel,
and a newly-allocated string otherwise.
The caller should be prepared for the callback to run before
FE_PromptForFileName() returns, though normally it will be
run some time later.
Returns negative if something went wrong (in which case the
callback will not be run.)
