Remove dll-split.

This patch removes dll-split from the code base, the reason is dll-split
no longer makes any sense. It was designed to split a dll in two, but we
now already have many more symbols than would fit inside two dlls. So we
need a third one. This means there's no point in having to maintain this
list as it'll never work anyway and the solution isn't scalable.
