codemod: ZSTD_sequenceFormat_e -> ZSTD_SequenceFormat_e
...
since it's a type name.
Note: in contrast with previous names, this one is on the Public API side.
So there is a #define, so that existing programs using ZSTD_sequenceFormat_e still work.

SeqDef is a type name, so it should start with a Capital letter.
It's an internal symbol, no impact on public API.

tests: fix non-regular file test on GNU/Hurd
...
Since commit b21b03ca6 [1] the behaviour of writes to /dev/zero has been
fixed and now the non-regular file removal test no longer needs to be
done on /dev/random (which no longer works as random is not writable now).

Fix & fuzz ZSTD_generateSequences
...
This function was seriously flawed:
* It didn't do output bounds checks
* It produced invalid sequences when an uncompressed or RLE block was emitted
* It produced invalid sequences when the block splitter was enabled
* It produced invalid sequences when ZSTD_c_targetCBlockSize was enabled
I've attempted to fix these issues, but this function is just a bad idea,
so I've marked it as deprecated and unsafe. We should replace it with
`ZSTD_extractSequences()` which operates on a compressed frame.

Fail on errors when building fuzzers

Fails on errors when building fuzzers with `fuzz.py` (adds `Werror`).
Currently allows `declaration-after-statement`, `c++-compat` and
`deprecated` as they are abundant in code (some fixes to
`declaration-after-statement` are presented in this commit).

Fix bugs in simple decompression fuzzer ( #3978 )

Fixes 2 issue in `simple_decompress.c`:
1. Wrong type used for storing the results of `ZSTD_findDecompressedSize` resulting in never matching to `ZSTD_CONTENTSIZE_ERROR` or `ZSTD_CONTENTSIZE_UNKNOWN`.
2. Experimental API is used (`ZSTD_findDecompressedSize`) without defining `ZSTD_STATIC_LINKING_ONLY`.
