[patch] Fix ftpfs uploading behavior.

["Andrew V. Samoilov" <kai cmail ru>]

Hi!

This patch fixes ftpfs uploading behavior.
Now if file is opened for writting only it will be not retrieved
to temporary file before uploading.

This is first approximation.
Test it carefully please.

Regards,
Andrew V. Samoilov.

ChangeLog:

* ftpfs.c (ftpfs_fh_open): Open data connection and remove localfile
if file is opened for writing only.
(ftpfs_fh_close): New function to close data connection opened in
ftpfs_fh_open().
