Save data to log file

[GoogleCodeExporter]

Explaination of new feature

-L or --log-file will save all data to a log file.
iperf will quit with an error if the target file exists unless -A or --append 
is specified.
Both a client & server option.

Justification of new feature

I need to keep logs, sometimes.

Hmm, is there some reason this is preferred over just using shell redirection?

I would prefer to be able to output a complete test as one txt file. They can 
collect in a directory. Then get sucked into a db for later use.

I thought it was the --output command argument that would save the data to a 
specified file, but it doesnt work or I could be doing something wrong.

-c <IPaddress> --output data.txt
Somehow I could not find that data.txt file.

Looks like -o/--output existed in a previous version but in not in the current 
version.  The consensus in yesterday's meeting was that if --output existed 
then we should fix it, otherwise people should just use shell redirection and 
we'll mark this WontFix.  So, WontFix.

Thanks for the update.

Wouldn't it make sense to re-open this issue and state that it will use 
-o-/--output, instead? That way, it can be tracked easily.

Alternatively, I can open a new issue for support for it, if you prefer.

yes, -o/--output should be fixed. it's very misleading. in the version I have 
used, 2.0.5, the flag is documented in help, but does nothing (and gives no 
error).  this is very confusing and I wasted some time trying variations.  in 
windows io redirection seems shaky and all results don't seem to be flushed to 
the file after hard-cancelling the process.
