msan requires that we build all code with msan to avoid false positives.

This allows to cover
- another arch that x86, which is also very common
- an arch where char is unsigned
- a little-endian arch

This is running under qemu-user, so significantly slower and doesn't support
ptrace thus no address sanitizer etc. but at least the undefined sanitizer
works.

So developers get the 64bit results first

* Add: fuzzer files and modifications in config & compil
* add configure.ac change
* add minimize-corpus.sh
* add fuzzing directory and readme
* add to check if CC support libfuzzer
* Make workflow dump the crash POC
* Add debugging information
* Run fuzzing only once a week for now
