eval: Use generated hash to look up function list

Problems:
- Disables cross-compiling (alternative: keeps two hash implementations which
  need to be synchronized with each other).
- Puts code-specific name literals into CMakeLists.txt.
- Workaround for lua’s absence of bidirectional pipe communication is rather
  ugly.
