* All copyright lines now have -2020 instead of -present
* All copyright lines include "Facebook, Inc"
* All licenses are now standardized
The copyright in `threading.{h,c}` is not changed because it comes from
zstdmt.
The copyright and license of `divsufsort.{h,c}` is not changed.
The `numFiles` variable wasn't updated, so the fuzzer didn't do anything.
I did two things to fix this:
1. Remove the `numFiles` variable entirely.
2. Error if we can't open a file and print the number of files tested.
