d69d8f904c Make the fuzzers more reproducible
We want to be in the same global state each time we come in
FuzzerTestOneInput(). There are various reasons why we might not be that
include:
- Initialization that happens on first use. This is mostly the
  RUN_ONCE() things, or loading of error strings.
- Results that get cached. For instance a stack that is sorted, RSA
  blinding that has been set up, ...

So I try to trigger as much as possible in FuzzerInitialize(), and for
things I didn't find out how to trigger this it needs to happen in
FuzzerTestOneInput().

ad4da7fbc0 Add a FuzzerClean() function
This allows to free everything we allocated, so we can detect memory
leaks.

33e49fda96 Fix strict-warnings build
The i2d_SCT_LIST function is declared as __owur, therefore we need to check
the result or a --strict-warnings build will fail.
