msg: change --msglevel, reduce legacy glue

Basically, reimplement --msglevel. Instead of making the new msg code
use the legacy code, make the legacy code use the reimplemented
functionality.

The handling of the deprecated --identify switch changes. It temporarily
stops working; this will be fixed in later commits.

The actual sub-options syntax (like --msglevel-vo=...) goes away, but I
bet nobody knew about this or used this anyway.
