I'm about to start work on a board that will have an 0.4mm BGA on it and
it seems that while current kicad supports editing blind/buried vias
there's no support for generation of sane drill files (one file per
layer pair).

I'm not really that familiar with the source structure of pcbnew, does
anyone have any idea where I should start looking? I want to modify the
"export drill file" code to create multiple drill files from the base
filename as follows:

foo.drl (through-board plated holes)
foo-npth.drl (through-board unplated holes)
foo-1-2.drl (blind vias from front to inner1)
foo-2-3.drl (buried vias from inner1 to inner2)
etc.

It'd probably be fairly simple to add a filter to the export code to say
"only put vias between these layers in this drill file" and then call
that function for each pair of layers.
