[PATCH] Add xfer:log-dir parameter to write transfer_log in arbitrary dir.

Hello!

I think it would be convenient to specify arbitrary directory for=20
storing transfer_log (it is useful when several processes using lftp are=20
launched simultaneously, and we need to analyze transfer_log for each=20
process separately). Here is the patch, feel free to make=20
suggestions/corrections etc.
