edsp: use an ID mapping for the internal solver

Currently an EDSP solver gets send basically all versions which means
the absolute count is the same, but that might not be true forever (and
with the skipping of rc-only versions it kinda is already) and even if
it were true, segfaulting on bad input seems wrong.
