New GETINFO option, "bytes"

[Damian Johnson]

Thanks Anders! You're right - this is a highly requested piece of
information (dozens of times at least this year). If this makes it into the
control spec it might be nice to include an option for the total bytes
downloaded/uploaded verses since the last reset (sighup). Regardless,
keeping my fingers cross that something like this makes it in. Cheers!

PS. This option was included in a proposal that's currently in limbo, which
might give a possible option name:
