Previously it was considered a programming error to call these on
subprocesses created without the correct flags, but for bindings this
distinction is difficult to handle automatically.
Returning NULL instead does not cause any inconsistent behaviour and
simplifies the API.
We can’t do anything differently based on whether removing a file fails.

This changes it so when a segment is encoded it will be
normalized at parse time which ensures its valid and
it can more easily be compared with other uris.
It’s technically undefined behaviour in C to copy between two
potentially-overlapping regions of memory (just like it is when calling
`memcpy()`). This can easily happen with union members; and the ones in
`GScanner` in particular.
Fix that by copying through an intermediate variable.
