Martijn van Beurden 51e61ae99e Fix mistake in fuzzing seed corpus 
The seed corpus had a file that was supposed to cover replaygain
synthesis, but didn't have any replaygain tags. Because of the
fixed format of these tags, they aren't reasonbly reachable by
fuzzing without help

fuzzer capable of fuzzing most code of the flac executable

Martijn van Beurden 76e8f22b4c Clean up and add to fuzzer_encoder (v1) 
Now fuzzer_encoder_v2 has been running for quite some time and no
big (encoder) projects are coming, fuzzer_encoder is changed. This
will invalidate the current corpus which will take time to rebuild,
but I think this is a good moment to do so.

Martijn van Beurden 96b5e6d35a Check vorbis comment entry before copying 
Whereas in C vorbis comment fields are in an array, C++ actually
validates the comment before returning it. This means it needs a
little more checking.

Martijn van Beurden 5bc582b2c7 Fix some OOM metadata bugs, disable OOM checking in metadata fuzzing 
For now OOM emulation in fuzzer_metadata is disabled, as I really
want to get as much merged as soon as possible. Need to get back
to this at some point

Martijn van Beurden 1f21ae2702 Add write callback abort check to seeking fuzzer

This commit adds a check to ascertain the write callback isn't
called again
