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`.
