b5fb2e7c12 Add Tool to Diagnose Whether Corrupt Blobs are Plausibly Bit-Flips
I spend an increasing amount of my time looking at "Corrupted block detected"
failures in decompression. Not infrequently, I suspect that it is the result
of hardware failure, and that the blob has become bit-flipped or otherwise
corrupted somewhere along the line.

For that reason I was motivated to write a little tool to inspect blobs that
fail to decompress, to try modifying them, and then check whether they
decompress successfully. This seems like potentially a generally useful tool,
so I figured it might be worth putting in `contrib/`.

mort of open source project are using this extension for the import library.
The Win32 linker is supporting this extension, see

b3c9fc27b4 Optimized loop bounds to allow the compiler to unroll the loop.
This has no measurable impact on large files but improves small file
decompression by ~1-2% for 10kB, benchmarked with:

head -c 10000 silesia.tar > /tmp/test
make CC=/usr/local/bin/clang-9 BUILD_STATIC=1 && ./lzbench -ezstd -t1,5 /tmp/test

c89 and c90 are the same language. Old compilers like gcc 4.2.1 don't
know the c90 alias.
