3eaa525138 Fixed clash when projects are already using xxHash 
Undefing XXH_* macros allows the `.c` to build standalone without clashes. Removing `xxhash.c` and only including the header is the correct usage (according to `XXH_PRIVATE_API`).

edd9a07322 Code replicated in compression and decompression moved to shared headers 
`CHECK_F` macro moved to `error_private.h` (shared between `fse_compress.c` and `fse_decompress.c`). `ZSTD_limitCopy()` moved to `zstd_internal.h` (shared between `zstd_compress.c` and `zstd_decompress.c`). Erroneous build artefact `zstd.h` removed from repo.

7c420344d2 Single-file decoder script can now (optionally) create an encoder 
To complement the single-file decoder a new script was added to create an amalgamated single-file of all of the Zstd source, along with examples and (simple) tests.

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/`.

8ac29cc825 Correctness and tidy 
Test compilation performed with warnings. Author and license added. Test for failing grep on ancient OSX versions. Replaced the test image with something less noisy (which compresses better).
