Re: Adding error reporting to GtkFileChooser

That's technically an API change, but not an ABI change.  If
someone was to use function pointers to any of these it would
not match.

For lots of reasons stat() can fail:

1. Permission problems.
2. File not there anymore.
3. File too big.  [Bug 136082.]
4. Causes due to NFS or other remote file systems.

Right now, some functions like gtk_file_chooser_default_select_path display
an error dialog(!) when this happens.  (Bug 136024.)  That's absurd for
an API call.

The answer is to pass the error back to the caller.
