Use

git am < 00xxx.patch

Recompilation is done as before, not even a configure run is needed.

This layer is there already, it's the one named "outline", all lower  
case. What isn't there is code to calculate the offset of the lines  
and polygons on this layer, as I couldn't find existing functions in  
the remaining pcb source code and I lack the resources to write it  
myself.

So, feel free to add this. The 0023 patch roughly shows a good place  
to start.
