Make the function ZSTD_compressSequencesAndLiterals() available in kernel
space. This will be used by Intel QAT driver.
Additionally, (1) expose the function ZSTD_CCtx_setParameter(), which is
required to set parameters before calling ZSTD_compressSequencesAndLiterals(),
(2) update the build process to include `compress/zstd_preSplit.o` and
(3) replace `asm/unaligned.h` with `linux/unaligned.h`.

Expose the zstd headers in `include/linux` to avoid struct duplication.
This makes the member names not follow Kernel style guidelines, and
exposes the zstd symbols. But, the LMKL reviewers are okay with that.
Add the kernel wrapper API. This keeps the same API and semantics as the
existing kernel API with name changes to be more kernel style and avoid
symbol collisions with zstd.
