afb0aca739 zstreamtest : big tests are only enabled in 64-bits mode
to avoid requesting too much memory in 32-bits mode during MT tests

a3d9926c40 compression optimization opportunity
switch to single-pass mode directly into output buffer
when outputSize >= ZSTD_compressBound(inputSize).
Speed gains observed with fullbench (~+15% on level 1)

ce91b64f00 [linux-kernel] Update patches for v2
* Reduce stack usage of many zstd functions, none use over 388 B anymore.
* Remove an incorrect `const` in `xxhash`.

037466245f refactor ZSTD_check_compressionLevel_monotonicIncrease_memoryBudget()
use less macro statements
the initial version was meant to work with STATIC_ASSERT
but since it doesn't work and needs assert()
it's possible to rewrite it using normally compiled code
which is better for compiler.

Downside : the error message is less precise.
There is a DEBUGLOG(3,) to compensate.

813535105b added function to control monotonic memory budget increase of ZSTD_defaultCParameters[0]
It's a runtime test, based on assert(),
played once, on first ZSTD_getCParams() usage,
when ZSTD_DEBUG is enabled.

31af8290d1 ZSTD_estimateCCtx_advanced()
ZSTD_estimateCCtx() is now a "simple" function,
taking int compressionLevel as single argument.

ZSTD_estimateCCtx_advanced() takes a CParams argument,
which is both more complete and more complex to generate.
