Conform to style guidelines.
 - In class definitions, one-space indent for public/protected/private.
 - Multi-line initializer format puts comma at end of line.
Also:
 - Eliminate the long list of friends in Minidump by making swap() public.
   (People who need to access unknown stream types directly will need 
   access to swap() too.)
