Ok, here we go:

This patch has modifications to the rename and rm handlers in lib/ssh.c.
As tipped, I'm now just returning an error if rename fails due to
destination already existing.

In order to test this, I also had to make modifications to the file
delete handler at the same time, since it also returns an unknown error
to the user application if the file does _not_ exist, and thus I added
support for this return code at the same time.

Seems to work properly now, but it sure makes renaming slow for user
applications since the entire connection has to be reestablished between
rename, delete, and reattempt to rename (that's how it is right now for
                                         sftp it seems)

Well, hope you prefer this method.

Time for bed!
