rsync overall progress patch

[Victor Denisov]

I understand that it's impossible to know how many
files will be transferred, but it has field with overall size
of files to be synced. And I want to know size of files
that are already processed(not transferred, but transferred or skipped).
If I have this information I can provide some kind of progress.
It will not be very good progress(since it can go fast or slow),
but it can present some indication.

Rsync does not know what files it will need to send until it is
finished (or transferring the last file that it needs to transfer).
Also, when doing delta transfers it has no idea how much of a
particular file it will have to transfer until it is done with that file.

See the man page section on --recursive for more info.
