Summary: In this patch I am trying to get rid of the `Irrelevant` types from the signatures of the functions from the standard C library. For that I've introduced `lookupType()` to be able to lookup arbitrary types in the global scope. This makes it possible to define the signatures precisely. Note 1) `fread`'s signature is now fixed to have the proper `FILE *restrict` type when C99 is the language. Note 2) There are still existing `Irrelevant` types, but they are all from POSIX. I am planning to address those together with the missing POSIX functions (in D79433).
