dd954ea943 CFG: correct flow for lambda bodies 
Lambda bodies are parsed as nested do-blocks or normal blocks.
This is actually incorrect, as the body of a lambda can't have
parameters. However, we can "inline" such blocks to get the
desired control flow.

58baa33a3f Various changes to user-facing library 
- Remove `abstract` classes from public API.
- Align `Variable.qll` with rest of library.
- Introduce `Callable` class.
- Make `Pattern` class cover everything that can be on the LHS of an assignment
  and in a pattern (except special parameters such as `**param`).
