Details:

As talked about on the mailing list, it would be nice if duplicity had
progress metering.  In particular, one designed to work with --dry-run to
enable frontends to (1) run with --dry-run to know some maximum progress
number and (2) run a second time, showing progress that grows until it hits
the number from (1).

Since --dry-run doesn't do any file reading for performance reasons, the only
stat we can play with is SourceFileSize.  So progress metering (for backing up
anyway) should count up as SourceFileSize grows.

The attached patch does several things:
1. Improve logging support for machine-readable messages.  Messages can have
multiple arguments, and any log with a None string will only go to
machine-readable logs, not the user-visible ones.

2. When not running with --dry-run, grow SourceFileSize organically.  That
is, SourceFileSize grows as files are read, not in one lump sum every time we
look at a new file.  This lets us handle the case of files that are larger
than our progress interval.

3. Print progress after each volume, at verbosity 5.  When using --dry-run,
we only print to machine logs, because otherwise we'd print progress at each
file encountered, which would just generate spew.
