Description of problem:
Many Red Hat spec files contain obsoleted and/or legacy rpm tags, 
which should be replaced before the upgrade of RPM to 4.4.x - it 
will come, I guess (sooner or later).
  
Actual results / Expected results:
For most things,

  's/^Copyright:/License:/'
  's/^Serial:/Epoch:/'

over all spec files should do this for example. 

The tag 'RHNPlatform' will be obsoleted. More information about the
changes of RPM are in the RPM changelog. 

Additional info:
I assigned it to the distribution, because it maybe should done 
generally and not only per package.
