  resetting parameters.

caecd8c211 Allow user to override ASAN/MSAN detection 
Rename ADDRESS_SANITIZER -> ZSTD_ADDRESS_SANITIZER and same for
MEMORY_SANITIZER. Also set it to 0/1 instead of checking for defined.
This allows the user to override ASAN/MSAN detection for platforms that
don't support it.

9261476b7d [lib] Wrap customMem xor checks in parens for readability 
This clarifies operator precedence, and quiets cppcheck in
the Kernel Test Robot. I think this is a slight bonus to
readability, so I am accepting the suggestion.

2e5d73dd72 Use MEM_STATIC FORCE_INLINE_ATTR instead of FORCE_INLINE_TEMPLATE 
It adds `__attribute__((unused))` for __GNUC__, to eliminate `-Werror=unused-function` error.

0a69a6b1ca Let MSVC force inline ZSTD_hashPtr() function 
ZSTD_hashPtr() function was not expanded by MSVC, led to low performance compared to GCC.

Merge pull request #2311 from felixhandte/ddss-fix-cparam-derivation 
Fix Compression Parameter Derivation Bugs Introduced by DDSS Changes

8930c6e551 Use ZSTD_CCtxParams_init() to Init CCtxParams, not memset() 
Even if the discrepancies are at the moment benign, it's probably better to
standardize on using the one true initializer, rather than trying (and failing)
to correctly duplicate its behavior.

eee51a664a Fall Back if Derived CParams are Incompatible with DDSS; Refactor CDict Creation 
Rewrite ZSTD_createCDict_advanced() as a wrapper around
ZSTD_createCDict_advanced2(). Evaluate whether to use DDSS mode *after* fully
resolving cparams. If not, fall back.

- `assert()` `endDirective` in `ZSTD_compressStream_internal()`, for debug mode
- add relevant tests

06d240b8a7 Use All Available Space in the Hash Table to Extent Chain Table Reach 
Rather than restrict our temp chain table to 2 ** chainLog entries, this
commit uses all available space to reach further back to gather longer
chains to pack into the DDSS chain table.
